Handle pthread_*_init() failures consistently

Browse Source 
isc_rwlock_init() currently detects pthread_rwlock_init() failures using
a REQUIRE() assertion.  Use the ERRNO_CHECK() macro for that purpose
instead, so that read-write lock initialization failures are handled
identically as condition variable (pthread_cond_init()) and mutex
(pthread_mutex_init()) initialization failures.
