Exclude new SDLControllerManager field from Android autogenerated source

Field was added upstream in
libsdl-org/SDL@36c5809.

As is the case with the neighbouring `mHapticHandler` and
`mJoystickHandler`, `mDeviceListener` is exposed as protected in
`SDLControllerManager`, but the actual type of it (`SDLDeviceListener`)
is not qualified with an access modifier, which means it defaults to
package-private.

In C# land this would result an inspection but Java is just worse at
this I guess.
