ZTS: Fix zpool_expand_001_pos

The dRAID section of the zpool_expand_001_pos test would reliably fail
because the calculated expansion size assumed the dRAID top-level vdev
was created with a distributed spare.  Create the vdev as expected to
resolve the test failure.

This test case flaw was accidentally caused by changing the default
number of dRAID distributed spares from one to zero while dRAID was
being developed.

Additionally, remove zpool_expand_005_pos from the list of possible
faulty tests.  It appears to be passing consistently in my testing.
