Pass through -work to go build

[squeedee]

We had a test polution that i suspected was removing the intermediary go build files. I wanted to run ginkgo -r -work to prove it, but that's not an option.

I admit that go test -work ./... get's me there, but theres a small but time-consuming cognitive dissonance switching from ginkgo's syntax to go test's packages spec.

I think the flag gets passed in now but Ginkgo doesn't print out the compilation output. Will fix.

this is now fixed.
