Fix distro package lists for openSUSE 15

Explicitly pulling in packages that are dependencies of the main
package can cause issues with newer releases where those packages
don't exist anymore - e.g. python-swift is renamed to python3-swift.
similarly python-keystonemiddleware (which is a dep of openstack-swift)
is actually called python3-keystonemiddleware these days.
