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. Change-Id: Iccc103d557de13d17e4a3f59a0cad2f4a640c148
