kbuild: Use CRC32 and a 1MiB dictionary for XZ compressed modules

Kmod is now (since kmod commit 09c9f8c5df04 ("libkmod: Use kernel
decompression when available")) using the kernel decompressor, when
loading compressed modules.

However, the kernel XZ decompressor is XZ Embedded, which doesn't
handle CRC64 and dictionaries larger than 1MiB.

Use CRC32 and 1MiB dictionary when XZ compressing and installing
kernel modules.

kbuild: avoid long argument lists in make modules_install

Running "make modules_install" may fail with

make[2]: execvp: /bin/sh: Argument list too long

if many modules are built and INSTALL_MOD_PATH is long. This is because
scripts/Makefile.modinst creates all directories with one mkdir command.
Use $(foreach ...) instead to prevent an excessive argument list.

kbuild: support 'make modules_sign' with CONFIG_MODULE_SIG_ALL=n

Commit d890f510c8e4 ("MODSIGN: Add modules_sign make target") introduced
'make modules_sign' to manually sign modules.

Some time later, commit d9d8d7ed498e ("MODSIGN: Add option to not sign
modules during modules_install") introduced CONFIG_MODULE_SIG_ALL.
If it was disabled, mod_sign_cmd was set to no-op ('true' command).
It affected not only 'make modules_install' but also 'make modules_sign'.
With CONFIG_MODULE_SIG_ALL=n, neither modules_install nor modules_sign
is able to sign modules.

Kbuild has kept that behavior, and nobody has complained about it, but
I think it is weird.

CONFIG_MODULE_SIG_ALL=n should turn off signing only for modules_install.
If users want to sign modules manually, modules_sign should be offered.

Pull modules updates from Luis Chamberlain:
"Nothing exciting at all for modules for v6.3.

The biggest change is just the change of INSTALL_MOD_DIR from "extra"
to "updates" which I found lingered for ages for no good reason while
testing the CXL mock driver [0].

The CXL mock driver has no kconfig integration and requires building
an external module... and re-building the *rest* of the production
drivers. This mock driver when loaded but not the production ones will
crash.

All this can obviously be fixed by integrating kconfig semantics into
such test module, however that's not desirable by the maintainer, and
so sensible defaults must be used to ensure a default "make
modules_install" will suffice for most distros which do not have a
file like /etc/depmod.d/dist.conf with something like `search updates
extra built-in`.

Since most distros rely on kmod and since its inception the "updates"
directory is always in the search path it makes more sense to use that
than the "extra" which only *some* RH based systems rely on.

All this stuff has been on linux-next for a while"
