Add NetBSD CI job

@blackgnezdo any idea what's wrong with Cabal?

$HOME is undefined?

[blackgnezdo]

Hmm, cabal update does anything?

Ah, I can see it was done above.

[blackgnezdo]

$HOME is undefined?
Yeah, this does seem plausible though I'm surprised about cabal update being so sanguine about it.

These diagnostics indicate HOME=/

% env HOME=/ PATH=$PATH /usr/local/bin/cabal update

Cabal issue about this problem is full of suggestions which files in ~/.cabal to remove because people suspect they got broken.

It works now:

@blackgnezdo could you please make a PR with a fix, based on this branch?

[blackgnezdo]

I'm happy to send a bunch of #ifdef that I used for a bit locally. One thing that happened in the interim is some OpenBSD developers wrote up an OS fix which we are likely see in the next OS release (coming in ~5-months). So, I feel if we merge my hack into unix, it will remain there for eternity. Maybe we should hold on adding the workaround until somebody else wants it?

This should not block the CI setup that you so kindly built. Please land it independently?

It naturally occurred to me right away that it's not landable without a solution on either side. Tell me which way you prefer it.

I've managed to setup a CI for NetBSD as well. One more reason for #263.
