This adds udev rules/hwdb that sets RATBAG_DRIVER and RATBAG_SVG
properties to the event devices. We then use this property to select
the correct driver instead of checking the hardcoded list in the
drivers. Having this in a hwdb makes it easier for users to test
if drivers match their mouse with a system installed libratbag.
Each driver now has an "id" which is used to match the driver set
in RATBAG_DRIVER. A SVG can optionally be set as well.
All entries in the hwdb are currently without a name as that
information was not available in the hardcoded lists.
Note that this patch breaks the test-driver.
