grub: add git version
Recently grub git gained support for ARM builds (using u-boot or EFI as first stage loader) and with 2 extra patches we get support for 64-bit ARM as well. Buildtested for genericarmv7a, genericarmv8 and qemux86. The genericarmv8 build fails in do_package/strip due to a binutils problem.
