SuperBuild: GEOTIFF: patch to remove INSTALL_NAME_DIR

Superbuild/CMake/patch.cmake is a helper script to apply
.diff files using patch program. This helps us from making
copies of entire source file and copying them individually.
This was done for other patches (ossim, gdal etc..)
TODO: use this mechanism in other places
