Revert of Include file names in trace_turbo output (patchset #3 id:40001 of https://codereview.chromium.org/2083863004/ )

Reason for revert:
Many build bots are failing with a message of the form:

Missing or invalid v8 JSON file: /tmp/tmp2qcEUy_swarming/0/output.json

Can be relanded once we understand why these failures are occuring.

Original issue's description:
> Include file names in trace_turbo output
>
> The trace turbo output will overwrite itself when functions in different
> files share the same name. Output files now have the form
> `turbo-<function_name>:<opt_file_name>-<opt_phase>.suffix`.
