comps-sync pass 3: Subset of workstation

The mental model here is simpler if our base package set is truly a subset of
Workstation.

Extend `comps-sync` to also support deleting packages not in the Workstation
set.  The only exception here is that we still want `kernel-modules-extra`
which for some reason is only in `livecd-tools`...I don't understand that.
For now I added a `whitelist`.

The set of resulting changes here generally makes sense.  We lose some
random unnecessary stuff like `teamd` and `dracut-network`, and `mactel-boot`.
We gain things like the desktop background packages, `sshpass`, and some `qt`
bits.
