linuxthreads.old: cleanup a bit

Use __UCLIBC_HAS_TLS__ instead of USE___THREADS (although this LT implementation
will never support TLS).
Disable unused/unneeded members of the pthread_functions structure.
No redirect/forward for _pthread_cleanup_push/pop, it would have not worked anyway
due to the fact, that the structure member was not initialized. Disable it's possible
internal use in libc-lock.h.
Avoid using internals.h in libc_pthread_init.c (moving a prototype to pthread-functions.h).
