firewalld: repackage

[Prince213]

This PR fixes the firewalld package, which will pave the way for my upcoming PR adding nixos modules.
It now works as expected.

Related: #165882.

Closes #293778.
Closes #369440.
Closes #371129.

To test the changes, build firewalld and firewalld-gui locally and run executables in bin, observe that they run without errors in aforementioned issues/PRs.
