Use 3 bytes for __pad1 in pthread_rwlock_t for x32
Since long is 4 bytes for x32, we should use 3 bytes for __pad1 when
a long __pad1 is replaced by a byte __rwelision and __pad1.
* sysdeps/x86/nptl/bits/pthreadtypes.h (pthread_rwlock_t): Use
3 bytes for __pad1 for x32.
(__PTHREAD_RWLOCK_ELISION_EXTRA): Likewise.
