Fix distribution paths for resource files.

glib-compile-resources lists the resource files as absolute paths,
but SET_LOCAL_DIST expects relative paths; the result was that the
tarball code was looking for ${CMAKE_SOURCE_DIR}/${CMAKE_CURRENT_SOURCE_DIR}/foo.
This change strips off ${CMAKE_CURRENT_SOURCE_DIR} from the filenames
before passing them to SET_LOCAL_DIST.
