ZFS: multiple fixes to the zpool_import tests

* Don't create a UFS mountpoint just to store some temporary files.  The
  tests should always be executed with a sufficiently large TMPDIR.
  Creating the UFS mountpoint is not only unneccessary, but it slowed
  zpool_import_missing_002_pos greatly, because that test moves large files
  between TMPDIR and the UFS mountpoint.  This change also allows many of
  the tests to be executed with just a single test disk, instead of two.

* Move zpool_import_missing_002_pos's backup device dir from / to $PWD to
  prevent cross-device moves.  On my system, these two changes improved that
  test's speed by 39x.  It should also prevent ENOSPC errors seen in CI.

* If insufficient disks are available, don't try to partition one of them.
  Just rely on Kyua to skip the test.  Users who care will configure Kyua
  with sufficient disks.
