dd: correct behavior when status=noxfer

Browse source 
Correct the behavior of `dd` with the `status=noxfer` option. Before
this commit, the status output was entirely suppressed (as happens
with `status=none`). This was incorrect behavior. After this commit,
the input/output counts are printed to stderr as expected.

For example,

    $ printf "" | dd status=noxfer
    0+0 records in
    0+0 records out

This commit also updates a unit test that was enforcing the wrong
behavior.
