The verifySessionProtocol() method in the SecureTransport backend did not
properly handle TlsV1_0OrLater, TlsV1_1OrLater and TlsV1_2OrLater.
This commit teaches verifySessionProtocol() about them.
It also adds TlsV1_0OrLater, TlsV1_1OrLater and TlsV1_2OrLater to the
protocolServerSide() test in tst_qsslsocket.
Backport from 5.10 to 5.9 (LTS).
