Update init-repository.py to allow using upstream chromium repository.

The regular workflow now is just to clone the qtwebengine repository
and then execute the following commands.
  git submodule init && git submodule update --recursive && qmake && make
This will also clone a submodule called 3rdparty which contains the
chromium and ninja sources without pulling in further submodules
and without a complete history.

Developers that do want to have a complete chromium checkout instead
should not use the above command sequence.
Instead they should just clone qtwebengine, execute the
init-repository.py script, run qmake and make.
The init-repository.py script will then checkout the complete
chromium sources into a subdirectory called 3rdparty_upstream.
The location of these sources will be picked up by qmake automatically.
