5/n Make OTP source available in elp parse-all

Summary:
We need to OTP project to be available to load files from it in the erlang service.

Do this for `elp parse-all`, and insteady filter out otp files in the main processing loop.

It means the total file count is slightly overstated for the spinner, but no extra work is done.
