Adhemerval Zanella 71d260c107 nptl: Cleanup mutex internal offset tests
The offsets of pthread_mutex_t __data.__nusers, __data.__spins,
__data.elision, __data.list are not required to be constant over
the releases.  Only the __data.__kind is used for static
initializers.

This patch also adds an additional size check for __data.__kind.

Checked with a build against affected ABIs.
