Revert of Add --output-dir flag for page_runner.py. (patchset #2 id:40001 of https://codereview.chromium.org/616063004/)

Reason for revert:
Failing on all perf bots in generate_telemetry_profiles:

Traceback (most recent call last):

Original issue's description:
> Add --output-dir flag for page_runner.py to specify a custom directory for
> output profiling and results data.
>
> Motivation behind this flag: I've run into a bug where a run on a local device
> and a run on the try bots are showing different versions of the page. I wanted
> to use the android_screen_recorder_profiler.py to record the try bot version
> and see what it is actually showing. However, it currently tries to output the
> video to a temporary directory in /tmp (which I do not have permission to write
> to).
