Inspired by msg211764, bpo-20682

In short:
For address family of AF_UNIX or AF_UNIX_CCSID, getsockname() returns 0 if issued before a bind(). The address length is 0. This is always the case for sockets created by socketpair().

That is at least one possible explanation I found.

Have tested on AIX 6.1 and AIX 7.1 - transport.get_extra_info('sockname') returns None

Even if it is just in the spirit of bpo-29972 I hope this can be given a quick review and have yet one less test failing on the AIX bots.

Could this also be backported to Version 3.6?

Ignore this since 3.6 is in security mode.
