Do not produce different files for each run on the mozilla-central repository

[Luni-4]

When rust-code-analysis-cli was being run on the mozilla-central repository many times, the filenames of the output formats produced at each run were different. That was because the old code assigned filenames without considering that the thread scheduler picks up input files every time in a different order.

So, to avoid conflicts among files, we now use input file paths as output format filenames.

Thanks in advance for your review! :)
