[Buildroot] [PATCH] xserver_xorg-server: fix dbus/udev configure problem

[spdawson at gmail.com <spdawson@gmail.com>]

From: Simon Dawson <spdawson@gmail.com>

If both the dbus and udev packages are selected, then the configure step
for the xserver_xorg-server package fails as follows.

  configure: error: Hotplugging through both libudev and dbus/hal not allowed

The configure script no longer allows both the --enable-config-dbus
and --enable-config-udev options to be specified.

This patch changes the xserver_xorg-server makefile to use dbus in preference
to udev, when both are available.
