linux-user: Do not define struct sched_attr if libc headers do

glibc 2.41+ has added [1] definitions for sched_setattr and
sched_getattr functions and struct sched_attr. Therefore, it needs
to be checked for here as well before defining sched_attr, to avoid
a compilation failure.

Define sched_attr conditionally only when SCHED_ATTR_SIZE_VER0 is
not defined.

linux-user: Fix strace output for s390x mmap()

print_mmap() assumes that mmap() receives arguments via memory if
mmap2() is present. s390x (as opposed to s390) does not fit this
pattern: it does not have mmap2(), but mmap() still receives arguments
via memory.

Fix by sharing the detection logic between syscall.c and strace.c.

linux-user: Fix setreuid and setregid to use direct syscalls

The commit fd6f7798ac30 ("linux-user: Use direct syscalls for setuid(),
etc") added direct syscall wrappers for setuid(), setgid(), etc since the
system calls have different semantics than the libc functions.

Add and use the corresponding wrappers for setreuid and setregid which
were missed in that commit.

This fixes the build of the debian package of the uid_wrapper library
(https://cwrap.org/uid_wrapper.html) when running linux-user.

linux-user: add strace support for openat2

This commit adds support for the `openat2()` to `QEMU_STRACE`. It
will use the `openat2.h` header if available to create user
readable flags for the `resolve` argument but does not require
the header otherwise.

It also makes `copy_struct_from_user()` available via `qemu.h`
and `open_how_ver0` via `syscall_defs.h` so that strace.c can use
them.

linux-user: add openat2 support in linux-user

This commit adds support for the `openat2()` syscall in the
`linux-user` userspace emulator.

It is implemented by extracting a new helper `maybe_do_fake_open()`
out of the exiting `do_guest_openat()` and share that with the
new `do_guest_openat2()`. Unfortunately we cannot just make
do_guest_openat2() a superset of do_guest_openat() because the
openat2() syscall is stricter with the argument checking and
will return an error for invalid flags or mode combinations (which
open()/openat() will ignore).

The implementation is similar to SYSCALL_DEFINE(openat2), i.e.
a new `copy_struct_from_user()` is used that works the same
as the kernels version to support backwards-compatibility
for struct syscall argument.

Instead of including openat2.h we create a copy of `open_how`
as `open_how_ver0` to ensure that if the structure grows we
can log a LOG_UNIMP warning.

Note that in this commit using openat2() for a "faked" file in
/proc will honor the "resolve" flags for
RESOLVE_NO_{MAGIC,SYM}LINKS for path based access to /proc/self/exe
(which is the only magic link we support for faked files).
Note it will not catch special access via e.g. dirfd. This is not
great but it seems similar to the exiting behavior when openat()
is called with a dirfd to "/proc". Here too the fake file lookup
may not catch the special file because no dirfd is used to
determine if the path is in /proc.

linux-user/syscall.c: eliminate other explicit LFS usages

Since we alwasy build with LFS enabled, and with -D_FILE_OFFSET_BITS=64
in particular, there is no need to use 64bit versions of various system
calls and constants, regular ones will do just fine. Eliminate a few
last uses of the following constructs in linux-user/syscall.c:
off64_t
ftruncate64()
lseek64()
pread64()
pwrite64()

This way it can be built on systems where the 64bit variants of
everything is not defined (since the system always uses 64bit
variants), such as on recent MUSL.

linux-user/syscall.c: drop 64 suffix from flock64 &Co

Since we are always building with LFS enabled, in particular
with -D_FILE_OFFSET_BITS=64, we should always have struct flock
mapped to the 64bit variant (with off64_t), and F_GETLK mapped
to F_GETLK64 etc, automatically.

So there should be no need to explicitly use the "64" suffix
for these things anymore.

Also fix a misleading comment near safe_fcntl telling us to
always use flock64 (since v2.6.0-1311-g435da5e7092a "linux-user:
Use safe_syscall wrapper for fcntl").

As per the deprecation notice in commit c7bbef4023:

The CRIS architecture was pulled from Linux in 4.17 and
the compiler is no longer packaged in any distro making
it harder to run the `check-tcg` tests. Unless we can
improve the testing situation there is a chance the code
will bitrot without anyone noticing.
