[PATCH] MINOR: ssl: rework smp_fetch_ssl_fc_cl_str without internal ssl use (no replies)

Hi Thierry,

This patch is related to « Capturing browser TLS cipher suites » thread.
I think it will be match the initial need but without internal ssl structure usage and.
work with openssl 1.0.2 to 1.1.1 and boringssl.
