[LTP] [PATCH] sigwaitinfo: Do not run invalid/undefined test cases

[Khem Raj]

These testcases run for eternity on musl

test_bad_address* cases are passing invalid pointers to a function; that's always UB
empty_set and timeout rely on the implementation-defined "may fail" for EINTR in sigtimedwait [1]

normally "may fail" is an "unspecified" but here the impl
is supposed to document it so it's "impl-defined"
