ooni.go: use 32 bit counter to signal interruption

Using a 64 bit counter has pitfalls. See Go documentation.

I don't want a refactoring or whatever to let these pitfalls
emerge in the future.

We just need one bit to signal we're done.

So use 32 bit, which shall be safe everywhere.

See https://golang.org/pkg/sync/atomic/#pkg-note-BUG.
