Kubilay Kocak 99f578691b converters/py-rencode: Fails to configure if cython is installed
ports r482774 removed USE_PYTHON=cython, likely due to it (cython) not
being explicitly declared as a dependency in setup.py:*_requires.

However, setup.py conditionally builds with cython if it is installed, but
the 1.0.6 source distribution (sdist) does not contain a .pyx file to build
with.

This leads to a configure/build error when cython is installed:

  ValueError: 'rencode/rencode.pyx' doesn't match any files

Upstream commit 5c928f14567fabc9efb8bbb8ac5e0eef03c61541 [1] via issue
#25 [2] adds the required .pyx file to the sdist, which technically
addresses the "build with cython from the sdist" issue, but does not
fundamentally resolve the higher-level question: why build with cython when
a C source pre-processed by cython has already been produced for, and is
contained in, the source distribution.

A cython build (and the dependency on cython) does not appear to be
necessary, nor intended [3][4], nor recommended [5], even after #25 is
released, for sdist consumers.

The conditional code to build with cython should not be included in
setup.py, at least not as a default case, or without an explicit request
by the user to use cython, as an optional build method, for sdist consumers
(most downstream packagers and setuptools/pip users [6]).

This change removes the conditional check for Cython, leaving the standard
setuptools build_ext (with the packaged .c) file, as the build method.

While I'm here:

 - Canonicalise COMMENT (match seutp.py:description)
 - Add test target with post-patch target to make the tests dir a module
   usable by a setup.py test (via test_suite directive) target.
 - Honour CFLAGS: Remove forced (appended) -O3 arg from setup.py
