[issue8835] buildbot: support.transient_internet() doesn't catch DNS socket.gaierror

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

The nameserver responsible of sha2.hboeck.de is down and this hostname is used in test_ssl. The result is that all trunk buildbots are red (error).

support.transient_internet() should catch socket.gaierror.
