1. deps: backport 010897c from V8 upstream …

   This is a reland of nodejs#3165. The patch abates
   the truncation of script filenames in the perf-event output produced by V8.

   Original: v8/v8@03ef3cd
   Reland: v8/v8@010897c
   
   Original commit message:
     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.
