Consolidate pthread_atfork
The pthread_atfork is similar between Linux and Hurd, only the compat version bits differs. The generic version is place at sysdeps/pthread with a common name. It also fixes an issue with Hurd license, where the static-only object did not use LGPL + exception. Checked on x86_64-linux-gnu, i686-linux-gnu, and with a build for i686-gnu.
