libusbgx: add bbappend from meta-toradex-bsp-common

The libusbgx bbappend should be placed in the toradex-demos layer rather
than in the BSP layer. This bbappend is a demo image–specific
customization and should not be applied universally to all users of the
BSP.

Keeping this change in the toradex-demos layer ensures it only affects
demo images (reference images).
