nptl: SIGCANCEL, SIGTIMER, SIGSETXID are always defined
All nptl targets have these signal definitions nowadays. This changes also replaces the nptl-generic version of pthread_sigmask with the Linux version. Tested on x86_64-linux-gnu and i686-linux-gnu. Built with build-many-glibcs.py. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
