Add zpool_destroy_004_pos test case.

This test targets the ability of 'zpool destroy -f' to tear down the pool
even if there is activity on it.  In particular, this tests a background zfs
send | zfs receive.

zpool_destroy_004_pos tests the following combinations:

  - Data size of 1GB: sleep times 0.1 0.3 0.5 0.75 1 2 3
    The goal is to test the race conditions at various points during the
    process of 'zfs send' and 'zfs receive', with respect to when the 'zpool
    destroy -f' takes place.
  - Data size of 4/3 physical memory: sleep time 15
    The goal is to validate that the destroy process teardown time is
    orthagonal to the send stream size.

Each test point above looks like this:

  for sleeptime in <sleep times>; do
    Run the tests where the sender and receiver are the same pool
    Run the tests where they differ; destroy the sender
    Run the tests where they differ; destroy the receiver
  done

The tests in each step above perform the following:

  - Create the sender pool (and receiver pool if applicable)
  - Create a dataset on the sender, populate it, then snapshot it
  - Start the send | receive in the background
  - Sleep $sleeptime seconds
  - Do the forced destroy of the target pool, must succeed
  - Wait for the background subshell to exit non-zero
  - Verify that the target pool is indeed no longer visible
