mate-menus: update to 1.22.0.

The soname didn't actually bump numerically, however, packages say they require the new version. Let me know if this is the correct procedure.

Backing out the change to shlibs. I am realizing that this won't do anything for me since there wasn't a soname bump based on comments in issue 12165 and some research of my own. correct me if I am wrong here please.

You're right. Configure scripts usually detect version of dependencies by querying pkg-config, cmake files or some other mechanism, not by soname. If a package needs a new version of a dependency, it's best to put both of them in a PR together, that way the build system will build the dependency first, then the package and you will know whether it works or not.

Alternatively, you can wait for the dependency to be merged and then rebase the PR that needs the newer version on top of master to make it pass travis.
