Desktop: remove geoclue agent

[danirabbit]

Goes hand in hand with elementary/switchboard-plug-security-privacy#148 and elementary/default-settings#279

The agent doesn't work with newer version of GeoClue, but the portal does work, so this is part of switching over

Sorry if I comment in wrong place, I am trying to follow this change in NixOS but got stuck. I am actually trying to do some testing with flatpak com.belmoussaoui.ashpd.demo, for some reasons with the change I can make location requests but no longer can get a LocationUpdated response, this is not the case when I have either pantheon-agent-geoclue2 or geoclue-demo-agent installed (natively). Since ubuntu's geoclue-2.0 package provides geoclue-demo-agent, does that mean starting from now we need to enable it in NixOS also? 🤔

We have geoclue 2.7.0 and elementary/default-settings#279, elementary/switchboard-plug-security-privacy#148 are backported when testing.

Can you open a new issue report on elementary/portals?

From my understanding, geoclue doesn't use agents at all anymore and now only supports the location portal

@bobby285271 so I just tested on a fresh daily ISO here with no pantheon-agent-geoclue2 and I was able to get location for both the system timezone (which is using geoclue directly) and from Atlas (which is using the location portal)

@danirabbit Hi, just to make sure, does pgrep -fa demos prints something like /usr/libexec/geoclue-2.0/demos/agent (which is the "geoclue-demo-agent" I mentioned above)? I wonder if the location still works if we kill these process

Edit: I downloaded a daily ISO, cannot test much but I guess the problem also exist there? 🤔
