Remove redundancy in section hypotheses of kernel entries.
We only do it for entries and not declarations because the upper layers rely on the kernel being able to quickly tell that a definition is improperly used inside a section. Typically, tactics can mess with the named context and thus make the use of section definitions illegal. This cannot happen in the kernel but we cannot remove it due to the code dependency. Probably fixing a soundness bug reachable via ML code only. We were doing fancy things w.r.t. computation of the transitive closure of the the variables, in particular lack of proper sanitization of the kernel input.
