nptl: Use SA_RESTART for SIGCANCEL handler
The usage of signals to implementation pthread cancellation is an implementation detail and should not be visible through cancellation entrypoints. However now that pthread_cancel always send the SIGCANCEL, some entrypoint might be interruptable and return EINTR to the caller (for instance on sem_wait). Using SA_RESTART hides this, since the cancellation handler should either act uppon cancellation (if asynchronous cancellation is enable) or ignore the cancellation internal signal. Checked on x86_64-linux-gnu and i686-linux-gnu.
