Several sanitizer tests hang indefinitely on NetBSD: ``` MemorySanitizer-Unit :: ./Msan-x86_64-Test MemorySanitizer-Unit :: ./Msan-x86_64-with-call-Test MemorySanitizer-X86_64 :: zero_alloc.cpp ThreadSanitizer-x86_64 :: signal_cond.cpp libFuzzer-x86_64-default-NetBSD :: reload.test ``` All of them loop and don't time out, so they need to be terminated manually for `ninja check-all` to complete. To avoid this, this patch skips the affected tests or subtests. Unfortunately, the Msan unit tests still hang on exit in `__cxa_finalize` even if all subtests are skipped with `llvm-lit -gtest_filter=-*`. Tested on `x86_64-pc-netbsd11.0`, `x86_64-pc-freebsd15.1`, and `x86_64-pc-linux-gnu`. (cherry picked from commit 782f1130177b2c792dc37f0923d21d187a4c150b)
