resolvconf: add fixes for busybox and make it work

resolvconf was missing a script and needed readlink which was in
/usr/bin.  Also the /etc/resolv.conf was not being correctly linked
to /etc/resolvconf/run/resolv.conf, which is fixed by the volaties
change which is now a file as opposed to created in do_install.

Ensure that the correct scripts for ifup/ifdown get installed and that
resolvconf is correctly enabled at startup
