astropy: TestStandardProfileHTTPSHub error after upgrade of OpenSSL to 1.1.0

With the latest release on Python (taken from 20161103 according to the Changelog), TestStandardProfileHTTPSHub.test_main gives an error on setup:

On Python-3.5, the behaviour is the same.

Main change in Python was the use of OpenSSL 1.0. The Python-2.7 changelog shows a few more SSL related entries:

• Issue #27691: Fix ssl module’s parsing of GEN_RID subject alternative name fields in X.509 certs.
• Issue #27850: Remove 3DES from ssl module’s default cipher list to counter measure sweet32 attack (CVE-2016-2183).
• Issue #27766: Add ChaCha20 Poly1305 to ssl module’s default ciper list. (Required OpenSSL 1.1.0 or LibreSSL).
• Issue #26470: Port ssl and hashlib module to OpenSSL 1.1.0. Closes: #835793.
