This reverts commit 416e3eb0c5.
This shouldn't be needed, when lorax will be called as a separate
process, not imported into pungi as a module (where python version
matters).
dracut dies with a usage message here if the version is passed after the
image name.
This is probably not needed as it turns out but I can't test that without a
full clean build which I don't have time for right now.
Fedora 23 forces every app that can be run under python 3 to be installed
as a python 3 app. This means lorax is installed as python 3 while pungi
remains 2.7. As soon as pungi is updated to python 3 (or the Fedora team
come to their senses) this package can be deleted.
