Remove Cheese from mandatory apps

[wjt]

Cheese was moved from the OS to a Flatpak in eos4.0. There has been a checkpoint between eos4.0 and eos5.0+, so we can now remove the flatpak-autoinstall.d rule that requires it to be installed. It follows that we can relegate it to "default" status, which in particular means that base images need no longer include it.

Depends on:

I see, so "apps_add_mandatory" apps are going to the base image, and "apps_add" go to default images like GIMP, Godot, etc.

The way it works is that base.ini uses the ${apps_add_defaults} list in its apps_del key for each remote.

https://github.com/endlessm/eos-image-builder/blob/master/config/personality/base.ini#L8-L14

The image builder adds up all the apps_add* keys for a remote, then subtracts all the apps_del* keys for that remote.
