resource-manipulation: rcs_common.so add missing depending library

rcs_common.so is also depending on liboc.so and libpthread.so, this
patch adds these dependencies to the build.
Add LIBPATH to make sure the libs will be found, this fixes a problem
in some jenkins tests.

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