Cleanup: flt.lttng-utils.debug-info: coding style

When I first wrote this component class, I was using the wrong coding
style standard. More specifically, the main problem is that the number
of tabs on breaking lines is wrong at bunch places in the debug-info
files.

I am currently working on this code and it annoyed me. So I fixed most
of it.
