Skip unneeded notice files for DATA modules.

Non-installable generated intermediate data modules can have
notice files attached when they're defined in the same LOCAL_PATH
as the installable module that depends on them. This makes uninstallable
DATA modules silently ignore the fact that the build doesn't know where
to install the notice file.
