Move is_wired_interface() from rc.d/wpa_supplicant into network.subr,
simplify it a bit, and make use of that method to determine if an
interface is a candidate for IPv6 rtsol rather than listing all of the
possible wireless interfaces that should _not_ get rtsol'ed.

This change is only relevant for 8.0+ unless the "wlan mandatory" code
gets ported back to RELENG_7.
