resolve: always align flags to 8th column and print CAA flags
Left-over unknown flags are printed numerically. Otherwise, it wouldn't be known what bits are remaining without knowning what the known bits are. A test case is added to verify the flag printing code: ============== src/resolve/test-data/fake-caa.pkts ============== google.com. IN CAA 0 issue "symantec.com" google.com. IN CAA 128 issue "symantec.com" -- Flags: critical google.com. IN CAA 129 issue "symantec.com" -- Flags: critical 1 google.com. IN CAA 22 issue "symantec.com" -- Flags: 22
