BUG: Fix origin&directions in CreateADICOMSeries - Update ITKv4 project

This problem is captured by issue 0002945 and the associated fix has been
pushed to ITK master.

During developer hangout of July 9th 2013, we discussed [1] what could
be the approach to build against a version of ITK including
commit df661440 without risking to break Slicer including new ITKv4 feature.

We concluded that working with ITK maintainers so that a patch release
ITK v4.4.1 including a list of carefully selected [2] commits is created was
the most reasonable approach.
Doing so ensures that only bug fixes are considered in the updated
version of ITK build by Slicer.

This commit update the ITKv4 external project so that the release
branch that will soon become ITKv4.4.1 is considered.

More particularly it include commit 9fa55c [3] fixing Slicer issue 0002945
