Fix CMake data and doc paths in Cygwin package

Override CMAKE_DOC_DIR and CMAKE_DATA_DIR cache entries on Cygwin early
enough so the new values are used everywhere.  Previously only some of
the uses were overridden.  Also set CPACK_PACKAGE_VERSION to the whole
CMake_VERSION so that the Cygwin MANIFEST file goes in the proper path.
