chore: drop vmlinux from assets

`vmlinux` (uncompressed kernel) shouldn't be much useful to the people
as it can't be booted directly with most of the boot tools (it's too
huge). We had it enabled for firecracker, but now firecracker has
support for decompressing `vmlinuz` on the fly.

So, to reduce confusion, make assets smaller, remove `vmlinux`.
