ucf debconf dialog should include the full path name

On upgrade from oneiric to precise, I was given a ucf prompt asking me what I want to do with the file "50-default.conf". There is not enough context here to know what file it's talking about. The debconf prompt should really list the full path to the config file for context.

(The file in question was /etc/rsyslog.d/50-default.conf, but I wouldn't have known that if I hadn't either peeked at the upgrade terminal or picked one of the options that shows me a diff.)
