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.

-Subject: [PATCH 4/4] Smack: Assign smack_known_web label for kernel thread's
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Assign smack_known_web label for kernel thread's socket in the sk_alloc_security hook
-
-Creating struct sock by sk_alloc function in various kernel subsystems
-like bluetooth dosen't call smack_socket_post_create(). In such case,
-received sock label is the floor('_') label and makes access deny.
