signals: join send_sigqueue() with send_group_sigqueue()
We export send_sigqueue() and send_group_sigqueue() for the only user, posix_timer_event(). This is a bit silly, because both are just trivial helpers on top of do_send_sigqueue() and because the we pass the unused .si_signo parameter. Kill them both, rename do_send_sigqueue() to send_sigqueue(), and export it.
