nptl: Add tests for internal pthread_rwlock_t offsets
This patch new build tests to check for internal fields offsets for
internal pthread_rwlock_t definition.  Althoug the '__data.__flags'
field layout should be preserved due static initializators, the patch
also adds tests for the futexes that may be used in a shared memory
(although using different libc version in such scenario is not really
supported).

Checked with a build against all affected ABIs.
