The best way of not getting something wrong is to not require it in the first
place...
All plugins now use DeviceInstanceId-style quirk matches and we can just drop
the prefix in all files. We were treating HwId=, Guid= and DeviceInstanceId= in
exactly the same way -- they're just converted to GUIDs when building the silo!
Right now vendor string is detected by walking up the udev chain
until a vendor is found. On some systems this is finding incorrect
data such as `Intel Corporation` for the vendor on the touchpad.
As the plugin only supports Synaptics devices, Correct it by hardcoding
vendor to `Synaptics`.
Sample output:
```
