I've tested a kernel with CONFIG_EFI_STUB added (thanks cking!).

This does boot with secureboot enabled, though the LXD agent fails to start due to lack of vsock.

So in addition to CONFIG_EFI_STUB, it looks like we also need:
 - CONFIG_VSOCKETS
 - CONFIG_VIRTIO_VSOCKETS
 - CONFIG_VIRTIO_VSOCKETS_COMMON

Which should give us the bits needed for virtio vsock.

The rest all looked good, so we should be fine with those tweaks and the kernel getting signed.
