Use ifconfig(8)'s "join" command by default

Its adoption went quite well, so install "join" rather than the old "nwid"
in new hostname.if(5) files and follow this trend in our wifi manuals.

OK deraadt sthen

Teach modern "inet autoconf"

This goes in line with hostname.if(5), unwind.conf(5), ifconfig(8)
as well as our installer.

OK deraadt

Build firmware for rsu(4), rtwn(4), and urtwn(4).
We have to install the files with new filenames (removal of "fw" from each of
the filenames) and change the driver to use the new filenames,
such that the package becomes irrelevant.

Discussed with deraadt@ and sthen@
