COMP: Build fails with ITK_USE_SYSTEM_TIFF

When turning ITK_USE_SYSTEM_TIFF the build fails with:

In file included from
/home/paulnovo/build-area/insighttoolkit4-4.3.1/BUILD/Modules/
Compatibility/Deprecated/test/DeprecatedIOTestDriver.cxx:6:0:
/home/paulnovo/build-area/insighttoolkit4-4.3.1/Modules/Compatibility
/Deprecated/test/itkTestDriverIncludeDeprecatedIOFactories.h:26:34:
fatal error: itkLSMImageIOFactory.h: No such file or directory
compilation terminated.

This fix removes the include for itkLSMImageIOFactory.h when
ITK_USE_SYSTEM_TIFF is on. The fix is done in the same way as in:

Modules/Core/TestKernel/include/itkTestDriverIncludeBuiltInIOFactories.h
