    remove overridesdir from the .pc file and add it to the gi module
    
    * having the variable in the .pc file caused issues parallel installing
      for different versions of python
    * putting it into the module allows us to give the correct directory
      based on which version of python you run the script from
    * access the var as such:
        import gi
        installdir = gi._overridesdir
