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> (cherry picked from commit 652b9fdb77d9fd056d4dd26dad2c14142768ab49) (cherry picked from commit ad9b8399537670a990572c4b0c4da5411e3b68cf)
