gh-148508: Add another common pattern for iOS SSL failures

[freakboy3742]

The test_ssl.TestPreHandshakeClose.test_preauth_data_to_tls_server test fails intermittently on the iOS buildbot because an SSL error doesn't raise the expected TLS handshake error.

This test already has an escape clause that allows a skip under certain error conditions (raising a ConnectionError, an OSError, or an SSL error with "wrong version number"). #148536 added a pattern for one type of iOS failure; this PR adds a second failure mode that is observed (simplifying the test into a single regex).

It also tweaks the iOS logging regex to strip an additional space; this should aid Bevedere in reporting stack traces when failures occur.
