admin: better handling of disabled mta-sts during self-check ...

if admin has disabled mta-sts for a domain, we still check for records &
policies, but won't mark it as error when they don't exist. we do now keep
warning that mta-sts isn't enabled, otherwise we would start showing a green
"ok".

this also fixes the mta-sts code returning ErrNoPolicy when mtasts.<domain>
doesn't exist. the dns lookup is done with the reguler "net" package dns lookup
code, not through adns, so we look for two types of DNSError's.

noticed a while ago when testing with MTA-STS while debugging TLS connection
issues with MS.
