setup.py: Adjustments to make setup.py run in py3k.
In py3k, subprocess.Popen.communicate's output are bytes objects. String
literals are Unicode objects. Thus, when a bytes object startswith method is
called, with string literals, it fails. What this patch does is:
* Convert the string (unicode in py3k) literals to bytes objects;
* As "bytes" is not a builtin in python < 2.6, it defines a "b" helper
function that merely returns its argument, as suggested by Antoine Pitrou.
