nptl: Replace some stubs with the Linux implementation

Browse Source 
The stubs for pthread_getaffinity_np, pthread_getname_np,
pthread_setaffinity_np, pthread_setname_np are replaced, and corresponding
tests are moved.

After the removal of the NaCl port, nptl is Linux-specific, and the stubs
are no longer needed.  This effectively reverts commit
c76d1ff514 ("NPTL: Add stubs for Linux-only
extension functions.").
