Disable mgr push sle16

[mcalmer]

What does this PR change?

mgr-push should not be shipped in the Client Tools for SLE16.
To prevent a submission the easiest was is to disable the build of the package and its dependencies until they are really required on SLE16.

Hmm, this would prevent mgr-push to build for Tumbleweed, and we ship it as part of TW Client Tools for Uyuni.

I'd consider this instead:
