    pf: Fix 'set skip on' for interface groups
    
    Previously if an interface type (without number), e.g. "set skip on vlan"
    or "set skip on em" was used, it would have the *undocumented* behavior
    of matching *any* interface of that type.
    
    Now it will only match an interface which is a member of the named group.
    And thus it works with interface groups of arbitrary names, e.g., one
    can "set skip on home" with "home" being the group containing interfaces
    "em1" and "tun0".
    
    This results in some changed behavior:
    
    If you currently use "set skip" with a physical interface type (e.g.
    "set skip on ix") you will need to add the interface to a group of that
    name: 'ifconfig ix0 group ix' or add 'group ix' to hostname.ix0.
    
    Interfaces cloned at runtime (e.g. lo, tap, tun, vlan) default to being
    in a group named after the interface type, so for these interfaces there
    will be no change in the behavior unless you have deliberately changed
    groups.
