[oe] [meta-xfce][PATCH] lxdm: provides fake gdmflexiserver for xfce desktop environment

[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

Xfce4 plugin 'actions' which stays in tray area provides a menu 'Switch
User' but the menu grayed out. It calls whether 'dm-tool' from lightdm
or 'gdmflexiserver' from gdm to support switch users.

Since recipe gdm has been removed from meta-gnome, create a fake
'gdmflexiserver' which calls lxdm to make menu 'Switch User' work
according to:
