log "list of supported TLS groups" only once

We had been logging it every two hours forever, even though it's based
on the version of OpenSSL we're using it so it will never change.

Fixes bug #41093.

The fix is an improvement on commit ba88ad6b which addressed #41058.

Not adding a changes file since those commits haven't gone out in a
release yet either.
