[aur-general] Merge and orphan request: jhbuild and jhbuild-git

They[1][2] both build jhbuild from git repository, and they both fail to build because of lacking 'yelp-tools' in their dependencies. Both maintainers seems inactive in regard to this building failure. I'm not interested with maintaining. But at least they should be merged. jhbuild-git seems to be in a better shape.
