get rid of the assumption that the head of the alldevs list is the
"mainbus" device. this breaks when mpath is enabled because it
attaches before mainbus and therefore takes the head position.
have autoconf provide device_mainbus() which looks up mainbus_cd,
and use that instead.
discussed with deraadt who just wants mpath stuff to move forward
despite there being many ways to shine this particular turd.
