[Buildroot] [PATCH v2 2/8] grub2-tools: new package

[Erico Nunes <nunes.erico@gmail.com>]

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.

Changes v1 -> v2:
  - bump to 2.02 instead of git, as discussed in the mailing list, and
  also 2.02 final release has finally been done this week.
  - grub 2.02 is not in the Buildroot default gnu mirror yet it seems.
  - needs wchar
  - add myself to the DEVELOPERS file
