34012d5af3 ci: Remove EXTERNAL_KERNEL_TAG variable 
The EXTERNAL_KERNEL_TAG variable is no longer needed.
For LAVA and bare-metal, we can override the KERNEL_TAG variable to fetch
both the kernel image and modules from a different tag than the default
mainline gfx-ci/linux kernel.

For LAVA, this also avoids the issue where jobs using EXTERNAL_KERNEL_TAG
would still have mainline kernel modules downloaded by the LAVA overlay.
