Look for gclient.py in find_depot_tools

Look for gclient.py in find_depot_tools

Many (but not all!) of our bots have a directory early in the PATH that
contains nothing but a script called 'gclient' and have the real
depot_tools directory later on in the path. This looks for gclient.py,
which is in the real depot_tools directory.
