device: turn off "unmanaged unless IFF_UP externally" for vethlr/veth-not-software

We currently don't manage a veth inside a container despite we should because
it's an externally configured software interface and thus waits for IFF_UP.

Given veths are prevented from being managed outside of a container by an udev
rule anyway it's safe to lift the external IFF_UP requirement for them.
