systemd-logind: filter out non-signal messages from message filter 

It's possible to receive a message reply in the message filter if a
previous message call timed out locally before the reply arrived.

The message_filter function only handles signals, at the moment, and
does not properly handle message replies.

This commit changes the message_filter function to filter out all
non-signal messages, including spurious message replies.
