gcs gamepad: teach GCS that an accel is not a gamepad

Browse Source 
The gcscontrolgadget expects all gamepad devices to have
at least 4 axes of control.  The SDL layer (on Linux anyway)
will detect the accelerometer that's built into some laptops
as a gamepad with 3 axes.

This change prevents the accel from being selected and
subsequently flooding the console with errors from
gcscontrolgadget every 10ms.
