unable to select wireless interface during install time on 11-CURRENT after the wireless subsystem rewrite

[Oliver Pinter]

Hi all!

After the "recent" wireless rewrite from Gleb, the enumeration of
wireless interfaces has gone from the bsdinstall.

This line: https://github.com/HardenedBSD/hardenedBSD/blob/hardened/current/master/usr.sbin/bsdinstall/scripts/netconfig#L52
return no entry, because the wlan interface not exists.
