Adds ability to disable ReadWriteLock on platforms (eg Android) that use pthreads but do not support pthread_rwlock.
​https://bugs.webkit.org/show_bug.cgi?id=30713

• wtf/Platform.h: Modified. Defines HAVE_PTHREAD_RWLOCK for all platforms currently using pthreads.
• wtf/Threading.h: Modified. Use pthread_rwlock_t only when HAVE_PTHREAD_RWLOCK is defined.
• wtf/ThreadingPthreads.cpp: Modified. Build ReadWriteLock methods only when HAVE_PTHREAD_RWLOCK is defined.
