Add a loadable module for tap(4).
The code was already modularized, we simply didn't build the loadable
module.
Note also that since the tap(4) device can be reasonably accessed by
either creating a device instance (using ifconfig(8)) or by opening
/dev/tap, we need to create both if_tap.kmod and tap.kmod (similar to
what is done with tun(4)).
