Bug#939604: /var/lib/fwupdate/done not removed on uninstall

[dann frazier <dannf@dannf.org>]

Package: fwupdate
Version: 12-6
Severity: normal

During the apt upgrade transitioning me to fwupd, I noticed:

Unpacking fwupdate (12-6) over (12-5) ...
dpkg: warning: unable to delete old directory '/var/lib/fwupdate': Directory not empty

Under that directory is a 0-length file called "done". Can that be removed
during postrm?
