Previously, psplash didn't go away at system startup.
The root cause is that rc checks the file '/etc/init.d/xserver-nodm' to
determine whether to exit psplash manually. So even if xserver-nodm is not
linked into runlevel 3, psplash doesn't exit.
This patch fixes this problem by letting the rc script check the file
'/etc/rc${runlevel}.d/S??xserver-nodm' to determine whether to exit psplash
manually.
