Remove some monkey patching used to allow git-upstream to work with GitPython releases older than 0.3.2, as the project requirements now depends on 1.0.1 or newer. GitPython release from 2.0.9 onwards removes the '__slots__' definition. This allowed for the git_dir attribute existence to be checked to determine whether to patch the Commit class imported from the GitPython project to add this attribute for older versions of the API.
