rpm: add multilib prefix for archs under deploy/rpm

Currently MACHINE_ARCH deploy folder is unique in multilib system, thus
a lib32 version of rpm package will override a normal rpm package if
its PACKAGE_ARCH is ${MACHINE_ARCH}.

Define different deploy folder for multilib architectures to avoid the
confliction.
