kernel: Fix symlinks

When installing a kernel package, the symlinks created by
update-alternatives should point to a path relative to KERNEL_IMAGEDEST
and not an absolute path to '/boot'.

Failing to do so causes problems when resolving the symlink inside some
bootloaders which mount the boot partition elsewhere.
