    pfctl: relax interface name requirement

    The FreeBSD network stack, for better or worse, does not impose any
    requirements on interface names. As such it's valid for an interface
    name to start with a number (or indeed, be something like '=E2=AD=90').

    Allow this in pfctl, and add a test case for the specific case of
    interface names starting with a number.

    Note that we don't support UTF-8 names fully, so those may still fail.
