Bug 500460

SUMMARY
At login, the ~/.var folder is populated with data for the Firefox Flatpak integration, and it creates the ~/.var folder even if Flatpak isn't installed.

This would be perfectly acceptable if it was somewhere more obscure, but creating a folder in my home directory for compatibility with software I don't use is very unfortunate. It being hidden doesn't improve the situation.

This is partially an upstream issue due to Flatpak's hardcoded use of the path, but support for changing it there is very low.

The behavior was introduced in this commit: https://invent.kde.org/plasma/plasma-browser-integration/-/commit/ebf6606463d73e7dd0a658340b369ab495da9b4a

STEPS TO REPRODUCE
1. Have plasma-browser-integration installed
2. Login

OBSERVED RESULT
A `.var` folder (along with contents) is present in home directory

EXPECTED RESULT
No folder generated unless Flatpak is installed (or at least, it would only populate the folder if it already existed)
