lomiri.lomiri-system-settings{,-unwrapped,-security-privacy}: init at 1.0.2

[OPNA2608]

Description of changes

Working towards #99090.

Lomiri System Settings is the main settings app for Lomiri. It's also one of the more integral parts of the lomiri shell & experience:

• It's a dependency for building it
• Some of the Ayatana indicators Lomiri displays have buttons that dispatch URL requests into the settings page
• Lomiri's first-time-wizard uses some of its QML modules in its setup pages
  • I don't think we'll keep the wizard enabled in our packaging, since it can't really configure much with the way NixOS works, but it's good to keep in mind that its QML modules get used in other places
• It's also one of the more convenient ways of graphically checking if URL dispatches (session indicator has a button that dispatches into it) and content-hub exchanges (wallpaper page lets you ask other applications for images) work as they should.

If my overview of dependencies isn't super off, then this should be one of the last big dependencies (if not the last big dependency) needed for building the lomiri shell.

I've submitted everything that I think is good to have for everyone upstream, but some things remain on our end:

1. Replacing the dependency on lomiri-keyboard with maliit-keyboard. I have so far been unable to get either of them working, but maliit-keyboard saves us a dependency. Debian is also patching this to maliit-keyboard, and lomiri-keyboard might get replaced by maliit-keyboard, so this seems fine to me.
2. There is an assumption that all plugins store their data under the same shared prefix - this affects plugin finding, loading, and localisation. I'm solving this via an envvar that points at the prefix to use, and a wrapper that symlinks files together & sets the envvar.

To ensure that everything works, I have packaged one of the external plugins (security-privacy) and added a VM test that:

• carefully checks that all pages for internal & wrapped external plugins don't crash & display the expected content, to check if the general wrapping is correct
• verifies that localisation is properly covered by the patch
