grub: Backport fix for largefile detection/use

This is inspired by musl porting, where grub's configure is enabling
largefile support based on glibc versions, instead an upstream patch
turns it into autoconf check

Update git version recipe

arm platforms use this recipe to provide grub and it needed fixes from
upstream so upgrade to latest tip of git and forward port patches as
well as drop the ones already applied upstream
