Subject: nptl: Move pthread_sigmask implementation to libc

This is part of the libpthread removal project:

  <https://sourceware.org/ml/libc-alpha/2019-10/msg00080.html>

A new symbol version is added on libc to force loading failure
instead of lazy binding one for newly binaries with old loaders.

Checked with a build against all affected ABIs.
