Pass additional dep target to slang

By "slang -a out/foo/bar/RenderScript.stamp ...", additional dep target will be added to the .d file,
something like:
out/target/common/obj/APPS/Fountain_intermediates/src/RenderScript.stamp ./fountain.bc: \
  frameworks/base/libs/rs/java/Fountain/src/com/android/fountain/fountain.rs \
  ...

Currently the .bc file is not used in the build system dependency graph, but the stamp file.
