support: add xinit script for the dbus user services

when running dbus under a graphical environment, it needs DISPLAY and
XAUTHORITY set in order to auto-launch graphical applications. but when
started via pam, or any way outside the gui, they won't be set. this
installs a script to be auto-ran by xinit, that loads the variables in
dbus.
