ZTS: Improve zts-auto_offline_001_pos

The zts-auto_offline_001_pos test could exceed the 10 minute test
limit and be KILLED by the test infrastructure.  To prevent this
speed up the test case by:

* Removing redundant pool configurations.  Each of the following
  vdev types is tested once: mirror, raidz, cache, and special.

* The block_device_wait function need only wait on the block
  device which has been removed as part of the test.
