Expand DIRAUTH_SKIP_CHECKS suppressions

DIRAUTH_SKIP_CHECKS prevented us from downloading (and by extension checking)
a dirauth's consensus documents, but it did not suppress other checks (presence
in votes, ORPort reachability, etc). This expands the suppression to cover
everything that references the DIRECTORY_AUTHORITIES global, which should
hopefully be everything.
