[PATCH v2 2/5] doc/prerst2man.py: Convert execfile to import

["W. Trevor King" <wking@tremily.us>]

excefile is gone in Python 3 [1].  Instead of exec-ing the
configuration, it's easier to insert the source directory in Python's
path [2], and just import the configuration.  With this change,
prerst2man.py is compatible with both Python 2 and 3.
