Fix generate_licenses Presubmit when working within chromium

Browse Source 
When working within chromium, we need to move up two more levels before
we can import the "find_depot_tools" module. Previously this was
managed by a loop that kept moving up until it found a directory named
'src', but this didn't work if the base-level webrtc code was not in
a directory named 'src'.
