[PATCH 3/7] lib: zstd: clean up Makefile for simpler composite object handling

[Masahiro Yamada]

Now, Kbuild nicely handles composite objects to avoid multiple
definition.

Makefiles can simply add the same objects multiple times across
composite objects.

The is clean-up from build system point of view.

I will apply this for the Kbuild tree.
