Gate gamepad support behind a feature flag

This is to make it possible to compile bedrock-pc without gamepad
support, which is useful when the target platform doesn't have the
libraries for udev (required by the gilrs dependency).

This commit is a bit of a hack, it'd be nice to implement this better
some day.
