BUG: Fix loading of MRC files

This commit reverts r22292

Commit r22292 updated ITK external project to explicitly
set Module_ITKReview and also removed the setting of ITK_USE_REVIEW.

Considering that since r22163, Slicer is built against the ITK release
branch and that commits deprecating ITK_USE_REVIEW have not been
back ported to the release branch, commit r22292 had the effect of:
  -> having an ITK built without module review at all.
  -> preventing the MRC IO plugin from being loaded
  -> preventing MRC file from being read into Slicer

COMP: Fix bug in writing origins to MGH files

Waiting Slicer makes use of the ITK remote module "itkMGHImageIO" (issue #3410),
this commit has been back-ported from Slicer/itkMGHImageIO@13f5e11ef.

It also has been tested by Hans as part of ITK.

BUG: Fix compile error introduced when backporting fix for MGH origin issue

The compile issue hasn't been detected earlier because only a visual check
between the original patch (Slicer/itkMGHImageIO@13f5e11ef) and
the back-ported one has been done (r22485).

This commit fixes the build issue and also confirm that the associated
Slicer tests now pass:

// --------------
Start 545: py_nomainwindow_test_slicer_mgh
[...]
test_saveShortCompressedNode (test_slicer_mgh.SlicerUtilLoadSaveMGHTests) ... ok
test_saveUnCompressedNode (test_slicer_mgh.SlicerUtilLoadSaveMGHTests) ... ok
// --------------
