Bug#318877: udpkg: Avoid error message on first run

[Petter Reinholdtsen <pere@hungry.com>]

Package: udpkg
Version: 1.01
Tags: patch

If I am not mistaken, udpkg will issue a warning when it is running
for the first time, because the status file is missing.  Here is a
patch to try to create the status file on the first run, and only
report an error if this failed.

I wrote this patch a long time ago, but never found time to test it.
Sending it here to make sure it isn't lost.
