There is the briefest start of coredump support in binfmt_flat. It is
actually a pain to maintain as binfmt_flat is not built on most
architectures so it is easy to overlook.
Since the support does not do anything remove it.

Apologies for hijacking this thread but it looks like we have people who
are actively using binfmt_flat on it.
Does anyone have any objections to simply removing what little there
is of coredump support from binfmt_flat?
No objections from me.
