BUG/MINOR: listener: enforce all_threads_mask on bind_thread on init

When intializing a listener, let's make sure the bind_thread mask is
always limited to all_threads_mask when inserting the FD. This will
avoid seeing listening FDs with bits corresponding to threads that are
not active (e.g. when using "bind ... process 1/even"). The side effect
is very limited, all that was identified is that atomic operations are
used in fd_update_events() when not necessary. It's more a matter of
long-term correctness in practice.

This fix might be backported as far as 1.8 (then proto_sockpair must
be dropped).
