[PATCH] Wayland X server uses xwayand.conf instead of xorg.conf

[darxus at chaosreigns.com]

xserver has a -conf argument you can use to point it at a different
xorg.conf.  Might be useful if weston / weston-launch had an ability to
pass this argument to xserver.

An old post of mine, fighting with this before I was having xserver
launched by weston:
