tests: Add tests for parsing specific DNS record types
Success and failure tests. This massively increases test coverage for parsing DNS records, although it doesn’t get it to 100%. It should now be useful enough to do more fuzzing on, without immediately getting trivial failures from the fuzzer. Signed-off-by: Philip Withnall <pwithnall@endlessos.org>
