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.
