Android: Enfore correct stick gate in overlay

Currently, the touch controller overlay uses a square gate for
sticks. This commit changes that so that it instead uses the
stick gate configured in the INI, which ensures that the values
sent to the core are appropriately scaled regardless of what
is configured in the INI and makes the overlay look nicer
if the INI is set to a stick gate that matches the graphics.
