grub: Improve Dockerfile to build GRUB faster

This commit improves the Dockerfile in order to remove a dependency of the whole source folder in pkg/grub. Currently, when the rootfs.cfg is updated, the whole GRUB is unnecessarily re-built. Copying only the needed files, we can make better use of Docker layers. Signed-off-by: Renê de Souza Pinto <[email protected]>
