tests: skip RENEGOTIATION-INFO SCSV in record_size cipher loop

TLS_EMPTY_RENEGOTIATION_INFO_SCSV appears in GetCipherNames() when
HAVE_RENEGOTIATION_INDICATION is set. It is a signaling value, not a
real suite; set_cipher_list accepts it but the handshake rejects it
with UNSUPPORTED_SUITE. Add it to record_size_skip_cipher's deny list.
