Missing run-time dependency on liblist-allutils-perl

[Mihai Moldovan]

Distro: Ubuntu 18.04.3 LTS
Package version: 2.6.0

After an upgrade from 16.04 to 18.04, debbugs (used via the CGI interface) stopped working.

Errors such as these are logged:

Looking at /usr/share/perl5/Debbugs/MIME.pm for instance, it really does use List::AllUtils, but no such run-time dependency is declared.

Installing liblist-allutils-perl is a valid workaround.
