Subject: [PATCH] Add a marker to rewritten desktop files

Add X-Flatpak=$app to rewritten desktop files.
Desktop files have multiple consumers, and this
makes it easier for them to know what to do.

(cherry picked from commit 66e91f55e87034208f33d10101009425a12207f6
 and e75cff6bb517badcb5c93177b4e9fe944c1e9e8d)
