BUG/MINOR: listener: always fill the source address for accepted socketpairs

The source address was not set but passed down the chain to the upper
layer's accept() calls. Let's initialize it like other UNIX sockets in
this case. At the moment it should not have any impact since socketpairs
are only usable for the master CLI.

This should be backported to 1.9.
