Gamepad: Fix parsing order for SDL2 controller databases
Created by: akien-mga
We were overriding values from gamecontrollerdb.txt
(current, updated
upstream) with gamecontrollerdb_205.txt
(legacy, SDL 2.0.5) and then
gamecontrollerdb_204.txt
(legacy, SDL 2.0.4).
There was a comment to warn about this but it seems it did not prevent using the wrong order for all this time...
Now gamecontrollerdb.txt
mappings will properly override outdated
ones present in the 204
and 205
variants.
