Continue reworking the coredump code so it's easier to follow and modify
in the future.
* Each method is moved into a separate helper.
* The cleanup code is simplified and unified.
* Entangle the dependency between the pipe coredump rate limiting and
the common exit path.
It's likely that there'll be more.
