Subject: [PATCH] Mock java17-runtime package to avoid issues using APT

Installing Openfire Debian package with `--force-depends` option results
in issues using APT next. Trying to install a new package in a container
will produce an error warning the user to use `apt --fix-broken install`
to resolve the unmet dependencies issue.
To avoid such an issue, build a fake java17-runtime package using
`equivs` and install it.
