grub2-tools: new package

Support tools to interact with GNU GRUB Multiboot boot loader.

In the context of Buildroot, some useful target tools provided by
grub2-tools are grub2-editenv, grub2-reboot, which provide means to
manage the Grub 2 environment, boot order, and others.

This package is also meant as a preparation step to be turned into a
host-package later and help decouple the target and host portions of the
actual Grub 2 boot loader package.
