LOG: [libcxx] Add missing member `cend()` to `MinSequenceContainer` (#175114)

The `MinSequenceContainer` (used in tests for `<flat_map>` and
`<flat_set>`) currently provides `begin()`, `end()`, `cbegin()` but no
`cend()`.
[[container.reqmts]](https://eel.is/c++draft/container.reqmts#36) lists
member function `cend` as one of container requirements, together with
`begin()` and others.
