sysdeps: tst-bz21269: handle ENOSYS & skip appropriately
SYS_modify_ldt requires CONFIG_MODIFY_LDT_SYSCALL to be set in the kernel, which some distributions may disable for hardening. Check if that's the case (unset) and mark the test as UNSUPPORTED if so. Reviewed-by: DJ Delorie <dj@redhat.com> Signed-off-by: Sam James <sam@gentoo.org>
