bpo-43562: fix test_ssl to skip on unreachable network (GH-24937) (GH-25047)

This test checks result code of the connection directly, so it never raises an exception that can be suppressed by `support.transient_internet`. Directly support skipping the test in case of unreachable network. (cherry picked from commit 29c451c) Co-authored-by: Carl Meyer <carl@oddbird.net> Co-authored-by: Carl Meyer <carl@oddbird.net>
