fix: remove RPMs after installing RPMs, to guarantee cleanup

This is necessary because the `rpm-ostree install` command lacks any way to exclude "recommended dependency" packages. It installs everything and the kitchen sink.

Therefore, installing something will often pull in a bunch of unwanted dependencies. The best we can do with the current situation is to run the removal after the install, so that users can remove those unwanted components manually and can be sure that they're actually removed.
