The "zpool status" output shows the full pathname for file-type vdevs,
but only the basename component for disk-type vdevs. In commit
bee6665, the "basename" command was dropped from altering the vdev
name used when searching the "zpool status" output. Consequently,
hot-disk sparing for disk vdevs broke since "zpool status" output
was now being searched for the full pathname to the disk vdev.

Parsing the "zpool status" output in this manner is rather brittle.
It would be preferable to search for the vdev based on its guid.
But until that happens, this commit adds back the "basename" command
to fix the vdev name breakage.
