Adds special treatment for stdout - if the user specifies '-o -' to perf record, the intent is that the event stream be written to stdout rather than to a disk file. Also, redirect stdout of forked child to stderr - in pipe mode, stdout of the forked child interferes with the stdout perf stream, so redirect it to stderr where it can still be seen but won't be mixed in with the perf output.
