Reject DHCP packets with no magic cookie
This patch adds an explicit check in the DHCP packet parser for
rejecting packets without a magic cookie, instead of relying on the
top-level try-catch-all in the parser.
This allows to add to DHCP error metrics this specific error.
It also allows to add two poor man's fuzzing tests that tries to find
additional gaps in the DHCP packet parser by
- trying to parse all subslices of a valid offer packet.
- trying to parse random byte arrays.
Test: covered by previously introduced malformed DHCP packet unit tests
+ additional fuzzing tests.
