x86: signal: handle_signal() should use set_current_blocked()

This is ugly, but if sigprocmask() needs retarget_shared_pending() then
handle signal should follow this logic. In theory it is newer correct to
add the new signals to current->blocked, the signal handler can sleep/etc
so we should notify other threads in case we block the pending signal and
nobody else has TIF_SIGPENDING.

Of course, this change doesn't make signals faster :/
