Fix ncm-cdispd forgetting about failed configuration modules

- Fix function used to run ncm-ncd not returning ncm-ncd status
- Use `CAF::Process` to execute ncm-ncd
- Properly retrieve ncm-ncd status (fix for the buggy value that has
always been returned)
- Improve debug logging

Fixes #4
we shouldn't hack around in ncm-cdispd. clean up the code and build up the command list.
also: 4 space indentation pls (and if you fix the indentation, make a single commit with only indentation fixes)
