devel/py-cbor2: Remove Python 3 support restriction

This package supports Python 3.x support, so allow it accordingly. It is
required for an upcoming www/py-autobahn update (Python 2/3 compatible).

During QA, a UnicodeDecodeError was observed running tests under Python 3:

File "/usr/local/lib/python3.6/site-packages/py/_vendored_packages/iniconfig.py", line 82, in _parse
  for lineno, line in enumerate(line_iter):
File "/usr/local/lib/python3.6/encodings/ascii.py", line 26, in decode
  return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 165: ordinal not in range(128)

pytest uses the py package, which vendors the iniconfig package, which
isn't unicode aware [1][2][3]. Patch out unicode characters from setup.cfg
accordingly until it's resolved.

While investigating the cause of the above issue, a fix for setup.cfg's
encoding was identified, which removes the need to set the locale via
USE_LOCALE so remove it accordingly.

While I'm here:

  - Pet portlint, spurious space at end of line in pkg-descr
  - Add LICENSE_FILE/TEST_DEPENDS/test target/NO_ARCH
