Alan Somers ec40ce8405 libzutil: don't read extraneous data in zpool_read_label ...

zpool_read_label doesn't need the full labels including uberblocks.  It
only needs the vdev_phys_t.  This reduces by half the amount of data
read to check for a label, speeding up "zpool import", "zpool
labelclear", etc.
