summary:

bpo-43562: fix test_ssl to skip on unreachable network (GH-24937) (GH-25046)

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 29c451c6989c3c94fa0a9facf187c24f3cbf2420)
