LU-3803 test: refine sanity test_161c

The test 161c is assume the $tdir will be in MDT0, but
actually $tdir(161d) left by 161a and 161b will be on
MDT1, which will make 161 fails, so delete $tdir before
testing 161c.

Add interop test condition.

Add more console output infomation.

LU-3754 mdt: Enable data_version control

When LU-1333 was landed, all HSM infrastructure was not yet landed and
it was not possible to archived a file. As a consequence, the original
patch did not compare on-disk archived data version and current file
data version.
Now, everything required is there and we should enable this
verification.
