Fix pthread_mutex regression test... undefined behavior does not

mean != EPERM in one test, minor changes to recursive mutex test.

remove printf in signal test signal handler, run test long enough
to ensure signal hander is called at least twice, reduce output.

Note: running these tests over a remote console may indicate bogus
falures due to console output latency.  Any test that takes longer
than 5 seconds to complete may be flagged as a failure.
