Revert "Android: Fix colorama-related pydeps"

This reverts commit eb669ff.

Reason for revert: Speculative, might have caused https://crbug.com/930538

Original change's description:
> Android: Fix colorama-related pydeps
> 
> //.vpython recently had colorama added to it, which means that adding the
> third_party version of colorama to then end of sys.path would result in
> the system package being chosen.
> 
> This fixes the import order of javac.py so that the third_party/
> one is chosen over system packages.
> 
> It also changes print_python_deps.py to *not* use vpython, so that
> it will match the behavior of GN / Ninja.
>
