Changes to camera apps installation and packaging

There have been several changes to how camera apps in postmarketOS are installed on devices:

• Device packages for devices with working cameras now have a subpackage, *-camera, that is installed by default. E.g. device-pine64-pinephone-camera.
• megapixels-gtk3 has been dropped from pmaports, this package was originally created to support sxmo's X11/DWM variant, but it is no longer required. megapixels should now work with this UI.
• megapixels-purism has been dropped from pmaports, the app was packaged in Alpine Linux aports as millipixels
• pmOS images for devices that do not support a camera will no longer include megapixels by default. Images for devices that do support a camera will have the relevant camera app installed by default.
• postmarketos-default-camera is a soft dependency, it can be uninstalled if having a camera app is not desired. Removing this package will remove any supported camera app from the install.

Action

Users with existing installs of pmOS on devices that support cameras can install postmarketos-default-camera to have the relevant camera app for their device installed:

$ sudo apk update
$ sudo apk add postmarketos-default-camera

Other users with devices that do not have working cameras can safely remove megapixels (with sudo apk del megapixels)
