net: allow wider regex in interface name

Zone IDs on Linux are network interface names. The regex we use to
determine valid IPs does not allow for non-alphanumeric characters
in the zone ID suffix. Some machines (including the RHEL Linux/s390x
machines from Marist) have zone IDs with a '.' character in them
which the regex in net.isIP rejects. This changes the regex.
