Merge ~kissiel/checkbox-support:fix-1864709-lshw-yields-list into checkbox-support:master

[Maciej Kisielewski]

lshw -json on focal yields a list of objects, which is considered a valid JSON, so I'm making this work as intended

[Rod Smith (rodsmith)]

I've tested on both Ubuntu 18.04 and Ubuntu 20.04 pre-release, and it works on both.

Thanks for the quick fix, Maciej!
