Fix mapi code generator for out-of-tree build

Use os.path.join() rather than hand-rolling it, so path is correct if
sys.argv[0] returns an absolute path.

(According to the python documentation, it's platform dependent whether
sys.argv[0] is a full pathname or not.  It probably also depends on how
the process was started...)
