oniro-image-common: depend on kernel-image

The rootfs already contains kernel modules so updating the image without
updating the kernel would cause a skew that would most likely prevent
the system from working.

On some platforms the kernel must be in a special area, as the
bootloader is more limited or closed, and the update process needs to
copy it to make progress.

On other platforms, we can use a more capable bootloader to load the
kernel from the rootfs directly. For all such platforms we want to add
the kernel-image package to the base oniro dependencies.

The kernel-image package is somewhat suboptimal, as ideally we would put
the kernel image into the root directory, making the /boot directory an
empty mount point for the boot partition.

Since doing this exceeds my skills and patience, the second best thing
will do.
