[PATCH] uml: unregister useless console when it's not needed

-mm in combination with an FC5 init started dying with 'stderr=1' because init
didn't like the lack of /dev/console and exited.  The problem was that the
stderr console, which is intended to dump printk output to the terminal before
the regular console is initialized, isn't a tty, and so can't make
/dev/console operational.

However, since it is registered first, the normal console, when it is
registered, doesn't become the preferred console, and isn't attached to
/dev/console.  Thus, /dev/console is never operational.

This patch makes the stderr console unregister itself in an initcall, which is
late enough that the normal console is registered.  When that happens, the
normal console will become the preferred console and will be able to run
/dev/console.
