    build: image: drop unused check-kernel-size recipe
    
    The recipe check-kernel-size is not used in the entire tree. Instead,
    we already check the size of the kernel image in Device/Build/kernel
    in image.mk via check-size function if KERNEL_SIZE is defined.
    
    Therefore, drop the function. Using it would be redundant anyway.
