support: Use syscall function instead of INLINE_SYSCALL_CALL

It fixes the build on ARM in thumb mode that requires an out of the
line helper (__libc_do_syscall) to issue the syscall.

io: Return UNSUPPORTED if filesystem do not support 64 bit timestamps

Some Linux filesystems might not fully support 64 bit timestamps [1],
which make some Linux specific tests to fail when they check for the
functionality.

This patch adds a new libsupport function, support_path_support_time64,
that returns whether the target file supports or not 64 bit timestamps.
The support is checked by issuing a utimensat and verifying both the
last access and last modification time against a statx call.

The tests that might fail are also adjusted to check the file support
as well:
