Merge Snap Camera into build chain

It nearly works already with https://github.com/visi0nary/android_packages_apps_Snap but once a picture is taken, the preview freezes... Camera2 works fine though so I am sure the callback needs to be changed in the app.

This happened after pushing the "Take Picture" button again when the old image was shown.
