grouper: Added pointer calibration file and libaes module.
This unbreaks --fde.
Issues before:
- Lack of pointer calibration made it near impossible to hit any keys on the osk-sdl keyboard.
- Lack of libaes module made it impossible to actually luksOpen the encrypted volume. That issue seems specific to the linux-asus-grouper kernel and does NOT happen with grate.
Fixes #1258 (closed).
