ltp: recent glibc calls syscall directly
The case of sigwaitinfo related to sigwaitinfo API failed.
glibc commit
8b0e795aaa44 ("Simplify Linux sig{timed}wait{info} implementations")
changed sigwaitinfo to call sigtimedwait, which calls rt_sigtimedwait
syscall directly.
So, an invalid pointer no longer crashes child process and test
reports failure. Fix it by accepting either crash or EFAULT.
