As of current master, importing netfilterqueue fails:

ImportError: .../lib/python3.4/site-packages/netfilterqueue.cpython-34.so: undefined symbol: PyString_FromStringAndSize

Issue #9 reports the same problem, but it was closed some time ago, and since then Python 3 support was supposedly merge into master.

So it seems that the problem reappeared again.

use elf.payload[:self.payload_len] for getting python string

This is more Cythonic way, documented here
http://cython.readthedocs.io/en/latest/src/tutorial/strings.html#passing-byte-strings

It compiles to
    __Pyx_PyBytes_FromStringAndSize(
        __pyx_v_self->payload + 0,
        __pyx_v_self->payload_len - 0)

Which is the Cython macro wrapper which handles both Python 2 and
Python3.

Fixes oremanj#17
