[Do not merge] build/linux: Move from go-appimage to sharun

Practical advantages over the unmaintained go-appimage:
- Nothing is wrongly copied on APP_DIR (files go to USR_DIR)
- Symlinks are maintained (good for canberra module)
- No need to patch LD interpreter (so works on CWD etc)

These advantages can appear to be small but they
reduce maintenance burden since we do not need to
make the manual adjustments above anymore.
