Before this, we'd see bizzare behavior of:
-> Adding changelog file (systemd.install)...
And, changelog files in the global section would not be added at all.
The code is clearly wrong here, as it references 'install' within a
loop of 'changelog' and 'install'. Let's use parameter indirection to
ensure that the proper file is identified and added.
