Sam Lewis b3509d491a chainntnfs: Add chainntfs lazy consumer test ...

This test adds a test for a consumer that registers for a transaction
confirmation but takes some time to check if that confirmation has
occured.

The test reveals a race condition that can cause btcdnotify to add a
confirmation entry to its internal heap twice. If the notification
consumer is not prompt in reading from the confirmation channel, this
can cause the notifier to block indefinitely.
