Gavin Atkinson 093b9154fd Allow bsdinstall to use WPA-Enterprise networks when installing. This
only allows basic username/password config, and does not provide the
ability to set any of the other WPA options.  Regardless, this is
generally sufficient to associate.

Perhaps in the future this could allow full configuring (e.g. being able
to set "anonymous identity", and perhaps some of the more obscure WPA
options), though perhaps that will better belong in bsdconfig when that
grows wlan config ability.
