setup.py: keep Python 2.3 compatibility

Though we only support Python 2.4 or greater, we should keep setup.py
compatible with earlier versions on the syntactic level. Otherwise
people will simply get a SyntaxError when trying to install Mercurial
with an old version of Python. With this change, the setup.py file can
be imported with Python 2.3 and we then issue a friendly error message
when we detect that Python is too old.
