Remove opensuse tumbleweed from our mirrors

Tumbleweed images were an interesting idea to add forward looking
testing of a very new and up to date linux distro. Unfortunately, the
images don't receive the attention they deserve to remain in our CI
system, and nothing seems to use the images anyway. Clean up our
opensuse mirrors and stop mirroring tumbleweed as one step in this clean
up process.

This depends on the change that removes the CI label/images.
