fix: bring up bonded interfaces correctly on packet

This probably fixes bonding in general if 2nd link in the bond is down.

For packet, set additional options for the bonded interface. In
networkd, add interfaces filtered out by link status as ignored to make
them available as bond subinterfaces.
