Subject: breakpad: treat node processes as browser processes

On Linux, to avoid the need to pass breakpad FDs to child node processes
spawned by child_process.fork(), each child process must re-initialize
breakpad independently, as a "browser" process. This patches
//components/crash so that it will correctly report 'ptype=node' as a
crash annotation.
