crunchgen(8): fix crunched application build with WARNS=6

This was revealed by the rescue build with a patch I'm working on to default
WARNS=6 everywhere. The issues resolved were:

- Missing prototype for _crunched_${ident}_stub in the *_stub.c generated
  bits
- Missing prototype for crunched_main
- Incomplete prototype for _crunched_${ident}_stub in the generated parts of
  crunched_main
- Literal strings in the stub table must drop const qualifier, unless we
  const'ify name
- f field in struct stub didn't have a proper prototype

Most of these issues are minor formalities and easily addressed.

I note that if my patch to eventually raise WARNS for the rescue build
lands, we'll need to bump the __FreeBSD_version requirement for
bootstrapping crunchgen and wipe out the rescue .OBJDIR if it's stale, which
we should be able to detect pretty easily from a couple of the issues that
have been fixed here.
