cmCTestGIT: Refresh index for local modifications 

We use 'git diff-index' to detect local modifications after pull.  On
some filesystems the work tree timestamps of a few files may be dated
after the index, making them appear as locally modified.  We address the
problem by using 'git update-index --refresh' to refresh the index and
avoid false local modifications.
