git-gui: Hide non-commit related commands when invoked as git-citool.

If the user is invoking us as git-citool then they want to perform a
single commit and exit quickly.  Since we are about to be a very short
lived process we should do what we can to avoid spending CPU time setting
up menus which the user will never use, like the fetch/push/pull menus.
