Subject: [PATCH 22/23] feat(hwdb): add hwdb module to install hwdb.bin on
 demand

Module to install hwdb.bin. Further extensions might make only selected
part of hwdb installable to save space. The module is not included by default.

Including the module adds 2MB of compressed data (on Fedora, the file has 12MB).

Installing hwdb.bin is needed in case of custom HW like a keyboard/mouse, or various interfaces.
