sstate: Add optimisation for useradd injected dependencies

useradd.bbclass adds sstate dependencies on base-passwd, shadow-native and
shadow-sysroot. Due to the way these are injected, they interact badly with
the other dependency validation logic and end up pulling in dependencies we
don't actually need. This patch adds code to optimise those cases out.
