common: Fix socket_connect_addr() not connecting using IPv6 in some cases

This extends the socket helper with functions to determine the "scope" and a
suitable "scope id" of an IPv6 address. Now socket_connect_addr() does not
trust the provided IPv6 "scope id" and always attempts to determine it using
the new helpers. This became a requirement during testing with remote usbmux
connections that provide a different "scope id" and thus might cause IPv6
routing to not work at all. Thus the "scope id" is only valid per host.
