temp/gnome-control-center: update to newer version.

Tested on my pinephone v1.1.

This is based on the latest tag from Purism (though I'm not sure why it's still on 3.34) and it adds a new "Devices" section which let's you select screen resolutions. This would probably come in handy for convergence phones.

Also changing password for current user in About -> Details -> Users scales correctly (woohoo), not sure if this was present before, but I remember having trouble with it.
