test/fuzz: add dnr packets

The structure of DNR options is considerably more complicated than most
DHCP options, and as a result the fuzzer has poor coverage of these code
paths.

This adds some DNR packets to the fuzzing corpus, not with the intent of
capturing some specific edge case, but with the intent to rapidly
improve the fuzzers' coverage of these codepaths by giving it a valid
example to begin with.

Also include an ndisc router advert with a few Encrypted DNS options,
for the same purpose.
