Better zfs_get_enclosure_sysfs_path() enclosure support
A multpathed disk will have several 'underlying' paths to the disk.  For
example, multipath disk 'dm-0' may be made up of paths:
/dev/{sda,sdb,sdc,sdd}.  On many enclosures those underlying sysfs
paths will have a symlink back to their enclosure device entry
(like 'enclosure_device0/slot1').  This is used by the
statechange-led.sh script to set/clear the fault LED for a disk, and
by 'zpool status -c'.

However, on some enclosures, those underlying paths may not all have
symlinks back to the enclosure device.  Maybe only two out of four
of them might.

This patch updates zfs_get_enclosure_sysfs_path() to favor returning
paths that have symlinks back to their enclosure devices, rather
than just returning the first path.
