Rework installation instructions

Since users should be capable of finding packages for their
distributions, this removes all instructions that point users directly
at specific packages.

The third party repositories like COPR have been kept, since those
are more difficult to find.

The structure of the installation instructions has also been reworked to
adjust for this and the post build instructions should be a bit cleaner
now.
