grub-efi: remove configure patch, simply seed the cache

grub-2.00-disable-help2man patches configure.ac to disable the help2man check
because we don't need the man pages.  It also then patches configure itself so
that autogen.sh doesn't have to be called for performance reasons.  However,
do_configure causes a full autoreconf so this optimisation is moot, and can
cause patch failures when an existing build tree is re-used.

Instead, simply use CACHED_CONFIGUREVARS to tell configure that it can't find
help2man.

-Upstream-Status: Inappropriate (Bitbake build environment)
-
-We do not need the man pages when building just the EFI payload for the target,
-all the tools are built for the host. This does not trigger GRUB's built-in
-cross-compilation check, so force it. After the change to configure.ac,
-autogen.sh was run in devshell and the resulting configure was used to generate
-the configure diff. The configure diff was included to avoid having to add
-autogen.sh to a do_configure_prepend() routine which would slow down the build
-unnecessarily.
