Subject: [PATCH] provide option in config to enable linuxefi

References: fate#314485
Patch-Mainline: no

As linuxefi module requires kernel 3.6 or later which supports EFI
handover protocol, it may not be able to load kernels without that
supports in place.

In case that things would break, and the linuxefi is really too young to
take over the position of "linux" kernel loader module, we introduce a
option GRUB_USE_LINUXEFI in the config and only explicit set it to true
will enable it. Example usage is

GRUB_USE_LINUXEFI=true grub2-mkconfig -o /boot/efi/EFI/opensuse/grub.cfg

This will output a grub.cfg which uses linuxefi in replace of linux and
enable verification of kernel signature if in secureboot enabled and
has shim exported protocols available.
