restorer: unblock only SIGCHLD previously blocked in criu
The purpose is to unblock previously blocked SIGCHLD, not all the
signals. IIRC, this block-unblock dancing is about a race where SIGCHLD
may come during switching to restorer blob, where CRIU handler function
is already unmapped - which will result in segmentation violation if
SIGCHLD wasn't blocked.
