Fix missing newlines in generate-certs.sh

Two openssl commands were merged onto the same line without a newline
separator, causing `openssl genrsa` to receive the subsequent `req`
command and its flags as extra arguments, which made it exit with
"Extra arguments given." and fail the CI smoke-sharkey job.
