Florian Weimer 7e625f7e85 nptl: Avoid expected SIGALRM in most tests [BZ #20432]
Before this change, several tests did not detect early deadlocks
because they used SIGALRM as the expected signal, and they ran
for the full default TIMEOUT seconds.

This commit adds a new delayed_exit function to the test skeleton,
along with several error-checking wrappers to pthread functions.
Additional error checking is introduced into several tests.
