Propagate installed files of Include_files_of dependencies

Some partitions (e.g. recovery) are transitive dependencies of
android_device module, and are not directly listed as partitions. This
change allows the installed files of `Include_files_of` partitions to be
propagated to the rdep filesystem module, so that it can reach the
android_device module and be disted.

Test: m nothing dist --soong-only && aninja -t query _dist_droidcore-unbundled
