BUILD: ssl: introduce fine guard for OpenSSL specific SCTL functions

SCTL (signed certificate timestamp list) specified in RFC6962
was implemented in c74ce24cd22e8c683ba0e5353c0762f8616e597d, let
us introduce macro HAVE_SSL_SCTL for the HAVE_SSL_SCTL sake,
which in turn is based on SN_ct_cert_scts, which comes in the same commit

(cherry picked from commit c47d676bd75e339f92faae430486ee337c45f134)
