    Fix regression in TLS session ticket disabling
    
    Commit 274bbced disabled session tickets for TLSv1.3 on top of the
    already disabled TLSv1.2 session tickets, but accidentally caused
    a regression where TLSv1.2 session tickets were incorrectly sent.
    Fix by unconditionally disabling TLSv1.2 session tickets and only
    disable TLSv1.3 tickets when the right version of OpenSSL is used.
    
    Backpatch to all supported branches.
