If the modified paragraph is referring to the idmapping mentioned in the
previous paragraph (i.e. `u0:k10000:r10000`), then it is `u0` that the
upper idmapset starts with, not `u1000`.
Fix this error and rephrase this paragraph a bit to make this reference
more explicit.

A kernel id is always created by an idmapping. Such idmappings are associated
with user namespaces. Since we mainly care about how idmappings work we're not
