Add a port for netdumpd

[markj]

I'd like to only build this for 11.x and 12, since it depends on libcasper. What's the right way to enforce that?

The new fancy way is IGNORE_FreeBSD_10= no libcasper support (wording up to you). Since anything before 10 is EOL already you don't need to worry about them.

Looks fine, with the distinfo issue fixed. Approved (be sure to note that since you are not a ports committer)

Can you run make makesum in the tree please? There's a missing _TIMESTAMP_ field here that is for some reproducibility work.
