tests: use `hg unbundle` in test-setdiscovery.t

This is testing how discovery between 2 well-defined repos works,
not that `hg pull` works with bundles. Switch to `hg unbundle` so it
works in environments where bundlerepos aren't supported.

 Function to test discovery between two repos in both directions, using both the local shortcut
 (which is currently not activated by default) and the full remotable protocol:
