Flip logic of checking whether a branch can report

Previously we checked if the branch being used was in a whitelist of
branches known to contain the reporting feature. Now, switch to checking
against a blacklist of branches known to *not* have the feature:
argonaut, bobtail, cuttlefish and dumpling.
