[PATCH v0] Make clear that passing --grub-mkimage to grub-install is not supported.

[Jon McCune <jonmccune@google.com>]

A reasonable alternative would be to completely remove all traces
of --grub-mkimage, and simply have it fail like any other unrecognized
flag to grub-install, but this will not be as clear to those who may
go looking for what has happened to --grub-mkimage.
