Warn when directory ownership differs between filesystem and package
We currently only warn if a directory's permissions differ, but using -Qkk
on my system shows that directory permissions tend to change in packages
reasonably frequently without notice. Provide a warning in such cases
so that it can be altered. Example output:
(1/1) reinstalling nginx
warning: directory ownership differs on /var/lib/nginx/proxy/
filesystem: 33:0 package: 0:0
