security/py-pyptlib: Limit Python version to 2.7

[loader]

Summary

I made a mistake in D11562, this port is not compatible with Python 3.

Proposed commit log message:

security/py-pyptlib: Limit Python version to 2.7

This port is not Python 3 compatible, failing with:

  File "/usr/local/lib/python3.6/site-packages/pyptlib/util/__init__.py", line 56
    m = re.match(ur'^\[(.+)\]:(\d*)$', spec)
                                    ^
SyntaxError: invalid syntax

Note that this will remove the Python 3 flavors from the port, do make sure that any port depending on it is also limited to 2.7.

The py36- package builds with a lot SyntaxErrors.

It seems it doesn't stop when an error is encountered:
https://github.com/python/cpython/blob/3.6/Lib/distutils/util.py#L463

Just a thought, maybe we can set a doraise=True here

compile(file, cfile, dfile, doraise=True)

Oh, and security/py-pyptlib is only required by security/obfsproxy,
obfsproxy is also a Python 2 port.

Current MAINTAINER (@cs) should be added to review

Commit log summary should describe (summarise) the change (commit), not describe the bug.

Something like Limit supported Python versions or Limit Python version to 2.7 with rationale/details ("Syntax Errors, missing explicit Python 3 listing in setup.py") in the body

Otherwise LGTM.

Thanks @koobs, I will add maintainer to review next time.
