Since a future patch will start displaying thin logical volumes for a
logical volume group thin-pool, add the ability to fetch the name
of the thin-pool.
This is accomplished by adding 'pool_lv' to the list of regex's and
when a "thin" lv segtype (groups[4]) is found, we can store the
thin-pool name.
