freebsd: attempt to re-enable image

The freebsd 'pkg' packages specified by the install script
weren't able to be added to the image because the version
of pip has been upgraded to py39-pip.   Because pkg failed
to install that command, all other packages (including
the installation of openjdk11 which is needed for jenkins
remoting to run) were also not installed.

Finally, let's change the subnet over to the one jenkins
will actually be using in order to ensure that there aren't
any surprises getting ssh working.
