meta-agl-{bsp,distro}: update kernel configuration for dunfell

Changes:
- Rework CAN qdisc patch application, as it is not required for 5.4
  or newer kernels, this includes adding a linux-agl-4.19.inc for
  BSPs using 4.19.
- Remove linux-agl-4.9.inc and associated patches, as no BSP uses 4.9
  at this point.
- Remove PREFERRED_VERSION_linux-yocto from poky-agl.conf so the
  default 5.4 linux-yocto kernel will be picked up.

Bug-AGL: SPEC-3302

-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.
