Fix issue #504

[Chlorophytus]

Hi, I'm doing some code stuff for Hacktoberfest and I figured I'd start off with this.

I am not sure how to go about this, but I kind of know C++.

I think this is one approach of getting Zypper to return exit code 104 if something isn't found in the zypper info command.

Let me know what else I need to do.
