Add LOCAL_EXPORT_C_INCLUDE_DEPS
This shouldn't be necessary for most makefiles, since we add
$(LOCAL_GENERATED_SOURCES) to this already included, but for prebuilts
that aren't actually prebuilts (Soong modules), we need to pass
dependencies so that the generated headers are built before being used.
