[spp] [PATCH] spp_vf: add specific libs in shared dir

[spp] [PATCH] spp_vf: add specific libs in shared dir

[ogawa.yasufumi]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

Common libs still need to use libs for specific worker processes. This
update is to add spp_vf specific libs to under `src/shared/secondary`.
