tools: debug_stream.py: Use cavstool.debug_slot_offset_by_type() 

The new cavstool.debug_slot_offset_by_type() opens an opportunity to
improve debug_stream.py usability a bit. If the debugfs file is not
found, then try to find the correct debug slot the correct slot using
cavstool direct access and debug_slot_offset_by_type().
