bpo-30175: Skip client cert tests of test_imaplib (#1320) (#1323)

* bpo-30175: Skip client cert tests of test_imaplib

The IMAP server cyrus.andrew.cmu.edu doesn't accept our randomly
generated client x509 certificate anymore.

* bpo-30188: Catch EOFError in NetworkedNNTPTests

test_nntplib fails randomly with EOFError in
NetworkedNNTPTests.setUpClass(). Catch EOFError to skip tests in that
case.

(cherry picked from commit 5bccca58b9b2b3a925b16750bedbd907695ea8d7)
