linux-user: fix O_NONBLOCK in signalfd4() and eventfd2() syscalls

On the hppa target userspace binaries may call signalfd4() and
eventfd2() with an old TARGET_O_NONBLOCK value of 000200004 instead of
000200000 for the "mask" syscall parameter, in which case the current
emulation doesn't handle the translation to the native O_NONBLOCK value
correctly.

The 0x04 bit is not masked out before the new O_NONBLOCK bit is set and
as such when calling the native syscall errors out with EINVAL.

Fix this by introducing TARGET_O_NONBLOCK_MASK which is used to mask off
all possible bits. This define defaults to TARGET_O_NONBLOCK when not
defined otherwise, so for all other targets the implementation will
behave as before.

This patch needs to be applied on top of my previous two patches.

Bug was found and patch was verified by using qemu-hppa as debian buildd
server on x86_64.

linux-user: fix O_NONBLOCK usage for hppa target

Historically the parisc linux port tried to be compatible with HP-UX
userspace and as such defined the O_NONBLOCK constant to 0200004 to
emulate separate NDELAY & NONBLOCK values.

Since parisc was the only Linux platform which had two bits set, this
produced various userspace issues. Finally it was decided to drop the
(never completed) HP-UX compatibilty, which is why O_NONBLOCK was
changed upstream to only have one bit set in future with this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=75ae04206a4d0e4f541c1d692b7febd1c0fdb814

This patch simply adjusts the value for qemu-user too.

linux-user: Add missing TARGET___O_TMPFILE for hppa and alpha

The hppa and alpha targets miss the #define of the TARGET___O_TMPFILE
and as such fail to run a trivial symlink command like

ln -s /bin/bash /tmp

which results in an -EINVAL return code.

Adding the define fixes the problem.
