pseudo: fix build for python3 based distros

Pseudo is not python3 friendly. It causes build failure on distros using
python3 as default python interpretor.

./maketables enums/*.in
  File "./makewrappers", line 327
    return """/* This function is not called if pseudo is configured --enable-force-async */
                                                                                           ^

  File "./maketables", line 76
    print "Flags: set for %s" % self.name
                            ^

make[2]: *** [Makefile:150: wrappers] Error 1
make[2]: *** Waiting for unfinished jobs....
make[2]: *** [Makefile:147: tables] Error 1

Those patches make pseudo works with python2 and python3.
