ipaddress: Allow listing addresses by type

Not sure why this was limited to ip-link before. It is semantically
equal to the 'master' keyword, which is not restricted at all.

The man page and help text adjustments include the 'master' keyword as
well since that is also supported but wasn't documented before.
