sign-kernel: Aggregate installing signed kernel action as signed-kernel.bst

The signed-kernel-endless.bst element using eos_sb_signer plugin does
not support install-commands. So, aggregate installing signed kernel
action from signed-kernel-endless.bst and signed-kernel-snakeoil.bst as
signed-kernel.bst. Then, deps.bst can depends on signed-kernel.bst
directly.

Fixes: 09276da ("sign-kernel: Fix the signed kernel image deployment path")
Fixes: #208
