Linux installer: validate the listen address instead of reporting every port as busy.

Browse source 
An entry like "all" made every port probe fail and the installer said
"port in use" forever. Aliases (all/*, local) are normalized, other
values must be an IPv4 address of this host, and port-free now tells a
busy port (exit 1) from a bad address (exit 3). Same check for set-bind.
