update_engine: remove redundant utils functions
utils::MapContainsKey and utils::SetContainsKey are the same
function and could be unified with more general templating, but
that would just be a reimplementation of base::ContainsKey so we
can just use that instead. Additionally, base::ContainsValue can
be used in place of utils::VectorContainsValue.
