[PATCH] gitk: automatically cd to $GIT_PREFIX

If gitk is ran as a shell alias it cannot find specified files in the
command line if ran in a subdir (because it's ran in the top-level
directory).

  cd Documentation/
  git -c 'alias.test=!gitk' test -- config.txt

The simplest way to fix this is to automatically cd to the specified
$GIT_PREFIX in the environment.
