Subject: [PATCH] engine: graph: We shouldn't complain on context cancellation

These are expected from our engine. We do care about timeout's and so
on. This allows os to return ctx.Err() whenever a <-ctx.Done() happens,
which is more idiomatic for what we really want, but which we weren't
thorough with before.
