nit: Sort of a pre-existing thing, but "dir" is terrible name for this. Could
you change it to e.g. python_exe or similar?

Actually, would using just "python" work on Windows? If so, let's do that.

It means that we'll start using python.bat from depot_tools but it seems to work
so why not. Did that change. Fewer lines of code. :-)

 #elif defined(OS_POSIX)
   dir = base::FilePath("python");
 #endif
 
   python_cmd->SetProgram(dir);
 
   // Launch python in unbuffered mode, so that python output doesn't mix with
   // gtest output in buildbot log files. See http://crbug.com/147368.
   python_cmd->AppendArg("-u");
 
   return true;
