Bug 1288625 - Part 2. Check pthread_cond_timedwait_monotonic_np. r=glandium

Android 64-bit doesn't have pthread_cond_timedwait_monotonic_np.  So we need check this function.  And although we don't turn on sandbox on Android, same define is used in security/sandbox/chromium/base/synchronization/condition_variable_posix.cc.
