BATS testing: Add SLES-12 to list of tested virtual machines

This adds SuSe Linux Enterprise Server 12 to the list of tested VMs.
SLES 12 is using systemd, so that the current RPM works
out of the box.

SLES12 however is already quite old and does not ship with java8, so this
required adding an opensuse repo.
