MINOR: ssl: rework smp_fetch_ssl_fc_cl_str without internal ssl use

smp_fetch_ssl_fc_cl_str as very limited usage (only work with openssl == 1.0.2
compiled with the option enable-ssl-trace). It use internal cipher.algorithm_ssl
attribut and SSL_CIPHER_standard_name (available with ssl-trace).
This patch implement this (debug) function in a standard way. It used common
SSL_CIPHER_get_name to display cipher name. It work with openssl >= 1.0.2
and boringssl.
