Description of problem:

Both `fedora-release` and `fedora-release-matecompiz` contain different versions of the file `/usr/lib/os-release`. The actual error message also mentions the `system-release` (resource?):

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages)

I'm affected as I usually install machines with a minimal base system (which pulls in `fedora-release`) and then, in a second step, install the rest of the system with e.g. `dnf install "@MATE Desktop"` which pulls in `fedora-release-matecompiz` and triggers the conflict.
Of course it's possible to use `--allowerasing` but setting up a system with all its dependencies like that makes me feel uneasy because I want dnf to choke on inconsistencies as they can hint towards real problems.


Version-Release number of selected component (if applicable):

- fedora-release-30-0.25.noarch
- fedora-release-matecompiz-30-0.25.noarch


How reproducible:

Steps to Reproduce:
1. Install a Fedora 30 minimal system so that `fedora-release` is installed.
2. dnf install "@MATE Desktop"


Actual results:

The error message above.


Expected results:

Something similar to Fedora 29. There, it's possible to install `fedora-release` and `fedora-release-matecompiz` side by side without problems.
