If the systemcall is not available ENOSYS is returned. Under glibc the statx implementation also has its own fallback logic. As AT_STATX_DONT_SYNC can't be implemented correctly in that fallback logic the wrapper will return EINVAL in case the emulation is needed and AT_STATX_DONT_SYNC is set. So also use our own fallback in that case. Fixes: util-linux#2409 Signed-off-by: Thomas Weißschuh <thomas@t-8ch.de>
