 Test pthread_rwlock_wrlock(pthread_rwlock_t *rwlock)

 It may fail if:

 [EDEADLK] The current thread already owns the rwlock for writing or
 reading.

 Steps:
 {{{
 1. Create and initialize an rwlock
 2. Perform a write lock via pthread_rwlock_wrlock()
 3. Perform a write lock _again_ with pthread_rwlock_wrlock without first
 unlocking rwlock()
 4. Test if returns EDEADLK or not.  Note the standard states "may" fail,
 so the test always passes even if 0 is returned.
 }}}

 https://github.com/haiku/open_posix_testsuite/blob/from_haiku_trunk/confor=
mance/interfaces/pthread_rwlock_wrlock/3-1.c

 Expected result: Test passed

 Actual Result: Test runs (i.e. attempts/acquires write lock), then HANGS.

 Tested on: Haiku hrev54815 x86 with Open POSIX Test Suite 1.5.2
