Bug#1024703: rename binary package to znuny too

[Daniel Baumann]

Package: znuny
Version: 6.4.3-1

Hi,

thank you for maintaining znuny in Debian.

It would be nice if you could also rename the binary package to match
the name of the otrs fork. Should you need help, let me know and I'll
send a patch.

Regards,
Daniel
