* latest GKE COS images do not have path for /usr/src. * deploygen updated to create kubearmor.yamls accordingly Detailed description: GKE supports multiple images types, viz COS and non-COS(Ubuntu, Debian etc). In case of non-COS images, the `/usr/src` contains the kernel headers. In case of COS, kubearmor internally downloads the kernel headers but still it used to mount `/usr/src` since we used a single yaml for COS and non-COS images. In the latest releases of COS images (for e.g., 1.22.6-gke-1000), the `/usr/src` folder is no longer present. The current changes now mounts /usr to `/media/root/usr` folder for GKE (only). The kubearmor code internally sets `BCC_KERNEL_SOURCE` to `/media/root/usr/src/linux-headers-KERNELVER`. Fixes kubearmor#579 Signed-off-by: Rahul Jadhav <nyrahul@gmail.com>
