BUG: Do not ENABLED_SHARED for GDCMIO

With shared libraries on windows and export specification with gcc,
memory leaking is being detected by valgrind. This should be
re-enabled when GDCM it self is enabled as shared with export
specifications.

COMP: Fix default wrapping with all modules

My previous patch (http://review.source.kitware.com/#/c/15885/) broke the wrappings
when starting from an empty build dir, as the ITKGroup_ variables are only set when
ITK_BUILD_DEFAULT_MODULES was set once to OFF.

This will fix the errors on the dashboard.
