[PATCH] uml: fix error output during early boot

The startup code panics a lot if anything goes wrong early on.  This is wrong
for several reasons, like the kernel isn't running, so you can't really be
calling into it yet, but the harm comes from useful error messages being
trapped in the printk ring where no one will ever see them.

This patch changes these panics to perror and printf in wrappers which also
exit.  Normal, informational, prints are also wrapped so that fflush(stdout)
is called after each one.  This is so the output appears in the correct
sequence in the event of an error.
