Revert "Add Manjaro 19.0 release"
As we're still discussing the best approach to take with Manjaro, let's revert the patch merged, do a release, and re-apply the patch once we solve the needed bits.
This reverts commit 4a673799 and the main reason for reverting it is to avoid having to carry a possible wrong entry forever.
