Subject: doh debug: rename SSLKEYLOG environment variable to OPENSSLKEYLOG

doh debug: rename SSLKEYLOG environment variable to OPENSSLKEYLOG

This avoids conflict between GnuTLS's built-in SSLKEYLOG and our hack
for OpenSSL. This would be important for instances which run
DNS-over-TLS using built-in GnuTLS
and at the same time DNS-over-HTTPS using lua-http (based on OpenSSL).
