Don Brady 0bcd1151f0 Fix ZED auto-replace for VDEVs using by-id paths
The change is simple -- restore the original code so that the VDEV 
path is updated when using by-id paths.  The more challenging part 
was to devise a second ZTS test, that would test auto-replace for 
'by-id' and help prevent a future regression.

With that new test, we can now do an A|B test with , and without, 
the fix to confirm that auto-replace for by-id paths works. The 
existing auto-replace test, functional/fault/auto_replace_001_pos, 
will confirm that we didn't break auto-replace for 'by-vdev' paths.

In the original functional/fault/auto_replace_001_pos test, the disk 
wipe (using dd) was not effective in removing the partitioning since 
the kernel was never informed of the wipe.

Added a call to wipefs(8) so that the kernel is informed and ZED will 
re-partition the device.
    
Added a validation step that the re-partitioning occurred by
confirming  that the GPT partition UUID changes.
