Server bug fix: Allow restarts when using port= option

If the Mandos server is configured to use a specific TCP port to
listen to (by using the port= option in mandos.conf or the command
line --port option), that port becomes unusable for a time when the
Mandos server is restarted, making restarts fail.  Avoid this by, if a
port number is specified, using SO_REUSEADDR when binding the
listening TCP socket to a port number.

* mandos (IPv6_TCPServer.server_bind): Set self.allow_reuse_address if
                                       a port number is specified.
