jkummerow e03df5229d Revert of improve perf_basic_prof filename reporting (patchset #1 id:1 of https://codereview.chromium.org/1388543002/ ) 
Reason for revert:
Suspected to cause crbug.com/539892

Original issue's description:
> improve perf_basic_prof filename reporting
>
> The buffer used for appending filenames to the string printed to the
> perf_basic_prof log was unnecessarily too small. Bump it up to be at least
> kUtf8BufferSize.
>
> Truncation of filenames makes it really hard to work with profiles gathered on
> Node.js. Because of the way Node.js works, you can have node module dependencies
> in deeply nested directories. The last thing you want when investigating a
> performance problem is to have script names be truncated.
>
> This patch is a stop-gap. Ideally, I want no truncation of the filename at all
> and use a dynamically growing buffer. That would be a larger change, and I
> wanted to have a quick fix available that can be back-ported to Node.js LTS
> release.
