generic/459 requires thin_check?

["Darrick J. Wong" <darrick.wong@oracle.com>]

Hi,

I noticed a test failure when running generic/459 -- it seems that this
test wants thin_check to be installed, doesn't explicitly check for it
(possibly because it is indirectly run by lvcreate), and therefore the
thin pool fails to activate.  I think this test needs to look for
thin_check and _notrun if it's not found.  Comments?

results/generic/459.out is as follows:
