Zbigniew Jędrzejewski-Szmek 9aa3d6b41e Revert "shared/install: create relative symlinks for enablement and aliasing" 
This reverts commit d6c9411072.

I still think this is something that needs to be done, but we're hitting some
unexplained failures, e.g. https://github.com/systemd/systemd/issues/22920.
So let's revert this for now, so -rc2 can be released, with a plan to return
to this after a release.

Closes #22920.
