basemode.collect_worker_info() takes the output of the info command to scan_worker.js, adds a few convenience fields, and then returns the dict to the caller.

Not all Firefox versions return the same structure for application.ini, AppConstants, and Ci.nsINSSVersion, and tlscanary is just blindly passing them through.

Expect this data structure to change between Firefox branches.
