Use IP based regex for rsyslog

From rsyslogd documentation:

  fromhost
    hostname of the system the message was received from
    (in a relay chain, this is the system immediately in
    front of us and not necessarily the original sender).
    This is a DNS-resolved name, except if that is not
    possible or DNS resolution has been disabled.

So it might be either hostname or IP address, however,
regex filter will work for IP address only.

This commit forces IP usage of IP addresses only.
