[autogardener] Skip printing clusters with no suspects

Don't even print the header for these clusters. It's not useful and just
adds noise to tree closure bugs. E.g. fxbug.dev/101184 had empty culprit
rankings for four different failure modes.

I initially thought it would be helpful to still show the failing test
name to make it clear that the autogardener recognized a cluster but
didn't find any suspects, but in practice I've realized it's not
helpful.
