[Buildroot] [PATCH 1/5] grub2: bump up version

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

Grub 2 version 2.00 which exists in Buildroot dates back from 2012 and
does not support new interesting features such as ARM support.

Despite it being the last official non-beta release, it makes sense to
bump Grub 2 to current master HEAD as the project has not been providing
regular releases since then.
Other distributions such as Fedora have also been shipping variations of
the newer "beta" releases.

Patch boot/grub2/0001-remove-gets.patch doesn't seem to be required
anymore as grub-core/gnulib/stdio.in.h has changed significantly since
"053cfcd Import new gnulib." and has another treatment for gets.
Patch
boot/grub2/0002-grub-core-gettext-gettext.c-main_context-secondary_c.patch
was a backport which is present after the bump and therefore is also no
longer necessary.
