test: move required test support files locally

[grahamwhaley]

Rather than have some of our required test support files live in /tmp,
let's install them in a local dir instead.

[grahamwhaley]

Marked as DNM so we can discuss (so really an RFC).

• the make check works as before
• the go test -bench=. gives the same results as before (see below)

I didn't realise we had some benchmarks ;-) I managed to run them with:

$ sudo -E env PATH="$PATH" go test -bench=.

It looks like we may have bitrotted though (as I suspect nobody runs these). The output I have from both the original and the modified-in-this-patch I get is:

@sboeuf - something you think we should fix? Any idea how?

[sboeuf]

Could you add a commit adding this whole directory to .gitignore ? This way, we won't have git tracking those files that we could add to a patch by mistake.

[grahamwhaley]

(oops, I meant to but forgot...) done and pushed
