[Buildroot] [PATCH v2 4/4] board/minnowboard-max: Add a X-based graphical defconfig

This commit adds a new defconfig to build a X-based
graphical system for the Minnowboard MAX board.
* The 'openbox' windows manager is chosen because it's simple
and lightweigth.
* Basic X apps are enabled (such as xrandr, xterm), so we
can at least get a console and change video mode.
* ALSA default configuration is provided, so HDMI audio
works out-of-the-box.
* OpenGL is supported.
Tested on Minnoboard Turot (which is Minnowboard Max compatible).

Changes from v1:
* Use an overlay instead of post-build.sh to customize the rootfs.
* Remove systemd usage, so we provide a minimum "audio and graphics"
setup.

+# Fixup startx so it doesn't start X on the controlling
+# virtual console. Apparently, this is a bug and we are
+# affected for our lack of a Display Manager.
+# See https://bugs.freedesktop.org/show_bug.cgi?id=87762
+#
+# I haven't found a way to do this without hacking startx
+# itself. The only change we are doing here is setting
+# serverargs to "vt1", see below.
+
+#
+# This is just a sample implementation of a slightly less primitive
+# interface than xinit. It looks for user .xinitrc and .xserverrc
+# files, then system xinitrc and xserverrc files, else lets xinit choose
+# its default. The system xinitrc should probably do things like check
+# for .Xresources files and merge them in, start up a window manager,
+# and pop a clock and several xterms.
+#
+# Site administrators are STRONGLY urged to write nicer versions.
