Fix various issues with the redundancy test suite.

- Remove randomness as a factor.  Instead of picking a random number of
  vdevs to create in the pool, always pick a specific subset that will
  adequately exercise redundancy, as well as make the test results more
  deterministic.
- sync_pool(): To complete, in addition to being scrubbed, the pool must not
  be in the resilvered state.  There appears to be a race in which the pool
  can have resilvered previously, and where this state isn't immediately
  reset upon scrubbing.  This is probably because the resilver state is only
  updated when the scan context runs, which may be delayed from the return.
- replace_missing_devs(): Don't recreate the vdev if it already exists.  In
  the case where damage_devs() is used (as opposed to remove_devs()), the
  vdev file already exists and its state reconciled (but not healthy until
  replaced later in this function).
