hwdb: Add hwbd definitions for maker tools

As originally added back in 2016 in 68ea57b21d ("Added support
for 3D printers to uaccess (ID_MAKER_TOOL)").

The first devices added would be 3D printers compatible with Flashprint
from Flashforge, as listed in this connector plugin:
https://github.com/Mrnt/OctoPrint-FlashForge/blob/master/octoprint_flashforge/__init__.py#L28
