inxi call failing on headless system

[fhdk]

When running

 $ mdd --force-telemetry
Welcome to MDD - The Manjaro Data Donor

[2025-09-12T14:25:05] ERROR calling inxi: Expecting value: line 1 column 1 (char 0)

...

Caused by prepare_inxi() which calls inxi with invalid argument

 $ inxi -Fxxx --output json --output-file print
Error 10: Unsupported value: print for option: output-file
Check -h for correct usage.

According to inxi -h - it should be a valid argument set - but it fails - could be an inxi bug 🤷

     --output  [json|screen|xml] Change data output type. Requires 
               --output-file if not screen. 
     --output-file
               [Full filepath|print] Output file to be used for --output.
