Flatpak repair

[meisenzahl]

Fixes #1981
Fixes elementary/flatpak-platform#108
Fixes #1741
Fixes #1986

As @mwleeds mentioned in #1523 (comment) we should patch

• Fix "Failed to read commit" error messages on install/update operations flatpak/flatpak#4765
• Fix marking static delta commits as partial ostreedev/ostree#2549

in https://github.com/elementary/os-patches.

The files provided in this PR could be a solution to repair broken Flatpak installations.

I was about to create patches for Flatpak and OSTree in https://github.com/elementary/os-patches. But apparently, the fixes are already included in the default Ubuntu packages:

• https://github.com/elementary/os-patches/blob/flatpak-jammy/common/flatpak-dir.c#L5948
• https://github.com/elementary/os-patches/blob/ostree-jammy/src/libostree/ostree-repo-pull.c#L2247

@mwleeds do you have any other idea what could be the reason that Flatpak installation break for users?

For example in #1981

The last commit adds a working prototype to fix Flatpak installations. It runs flatpak --system repair and flatpak --user repair in the background.

The functionality is implemented via an Action. We could add a button in case of an error during an installation or update that suggests the repair and triggers the action.

@elementary/ux would this be a solution we want to work on further?

@danirabbit after a fresh installation of elementaryos-7.0-stable.20230129rc.iso in VirtualBox, I also have the runtime error you see in the video. With the steps in the video I am able to fix the error using this branch.

I can confirm that this fixes the issue in a clean virtual machine, so let's goo 🚀
