Flatpak’s installed tests build Flatpak runtimes, among other things.
Upstream code does this by copying some programs on `PATH`
as well as some possible dependencies from host’s /usr.
We patch the code to use `nix-store --query --requisites`
to make the dependency discovery easier.
The Flatpak’s installed tests add `socat` to `PATH` and later run
`nix-store --query --requisites` on its location but it was failing with
error: path '/nix/store/qcyf7nq5vvfw32967sv4j6z190inrbrc-socat-1.7.3.4' is not valid
The issue occurred because, while the host Nix store is bind mounted into the test VM,
the VM’s store uses its own database that only contains the packages in the VM’s closure.
Since the test commands are not actually part of the VM but only passed through PTY,
the `flatpak.installedTests` derivation was not part of the VM’s closure, so `nix-store`
in the VM could not get information about its dependency `socat`.
Let’s make the `installedTests` of the tested package part of the test VM’s closure
by passing it as a global environment variable. This will also have the added benefit
that user no longer has to type the path when running the installed tests manually in the VM;
they can just use `gnome-desktop-testing-runner -d $TESTED_PACKAGE_INSTALLED_TESTS`,
which is much more conducive to tab completion.
