Rework Linux Kernel fragment applications

- All kernel recipes must inherit linux-agl.inc
- All kernel recipes for a given version (e.g. 4.9) should include
  linux-VER-agl.inc in order to avoid duplication (such as the SMACK
  label patch or security fixes)
- We enforce having merge_config.sh be invoked at the end, in order to
  make sure fragments will be applied.
- Add a new fragment for Raspberry Pi to ensure the Pi Touchscreen is
  still enabled.

With all of the above, we fix a number of minor issues as well, such as
platforms manually enabling NBD/RAMDISK for netboot as the previous
logic was not working in all cases.
