    Use a symlink to supercomand instead of pkgresources.load_entry_point

    This sppeds up startup a lot and thus makes bash completion much more
    responsive:

      $ gbp buildpackge --help
      real      0m0,573s
      user      0m0,532s
      sys       0m0,036s

      $ time python 
/usr/lib/python2.7/dist-packages/gbp/scripts/supercommand.py buildpackage --help
      real      0m0,051s
      user      0m0,040s
      sys       0m0,012s

    Closes: #853283
