BUG/MINOR: ssl: fix crt-list neg filter for openssl < 1.1.1
Certificate selection in client_hello_cb (openssl >= 1.1.1) correctly
handles crt-list neg filter. Certificate selection for openssl < 1.1.1
has not been touched for a while: crt-list neg filter is not the same
than his counterpart and is wrong. Fix it to mimic the same behavior
has is counterpart.
It should be backported as far as 1.6.
