nptl: Move rwlock functions with forwarders into libc

Browse Source 
The forwarders were only used internally, so new symbol versions
are needed.  All symbols are moved at once because the forwarders
are no-ops if libpthread is not loaded, leading to inconsistencies
in case of a partial migration.

The symbols __pthread_rwlock_rdlock, __pthread_rwlock_unlock,
__pthread_rwlock_wrlock, pthread_rwlock_rdlock,
pthread_rwlock_unlock, pthread_rwlock_wrlock have been moved using
scripts/move-symbol-to-libc.py.

The __ symbol variants are turned into compat symbols, which is why they
do not receive a GLIBC_2.34 version.
