event_reinit: always re-init signal's socketpair
Before this patch event_reinit() only closes the signal socketpair fds and
recreates them if signals have been added, but this is wrong, since socketpair
fds created on backend init, and if we will not re-create them bad things in
child/parent signal handling will happens (and indeed this is what happens for
non-reinit backends like select).
Fixes: #307
