Fix screenshot.py
Fix screenshot.py

build/android/screenshot.py was creating a DeviceUtils. Then grabbing
it's old_interface (i.e. an AndroidCommands) and calling screenshot on
that. That then called TakeScreenshot from
build/android/pylib/screenshot.py passing itself. But
build/android/pylib/screenshot.py expects a DeviceUtils, not an
AndroidCommands. So wrap the AndroidCommands back into a DeviceUtils
first.

build/android/screenshot.py could probably just call into
build/android/pylib/screenshot.py directly.
