things-manager: libTGMSDKLibrary.so: add missing depending library

libTGMSDKLibrary.so also depends on liboc.so, liboctbstack.so and
pthread, this patch adds these dependencies to the build.

Without this the dynamic loader will not automatically load these
libraries and it could result in unresolved dependencies at runtime.
