[Reportbug-maint] Bug#764888: reportbug: does not honor `-u urwid` option

[Andrew Kane]

Package: reportbug
Version: 6.5.1
Severity: normal

Dear Maintainer,

   * What led up to the situation?

I wanted to report a bug in a different package.
I didn't want to use the text interface. After all, why am I running X, right? ;^)

   * What exactly did you do (or not do) that was effective (or ineffective)?

First, I invoked `reportbug -u gtk2` but it failed as in #758619. (Marked as Resolved, but not fixed in Testing as of this writing.)
Then I invoked `reportbug -u urwid` which `man reportbug` reports as one of three valid options for th -u switch:
 "-u INTERFACE, --interface=INTERFACE, --ui=INTERFACE
   Specify the user interface to use.
   Valid options are text, urwid, and gtk2; default is taken from the reportbug configuration files."

   * What was the outcome of this action?

Reportbug starts in text mode with the following message:
"Ignored bogus setting for -u: urwid"

   * What outcome did you expect instead?

Expected a curses-like interface. TBH I'm not sure what the `urwid` interface is supposed to look like, but I think this isn't it.
