Brooks Davis 39c4f65c72 stddef.h/stdlib.h: Remove unused rune_t
This non-standard type is unused in the base system (__ct_rune_t or
__rune_t are used instead) and ports.  It has been around as long as our
current source repo, but we have avoided using it.  In sys/_types.h
where the __*rune_t typedefs are defined, the following appears in a
comment:

    NOTE: rune_t is not covered by ANSI nor other standards, and should
    not be instantiated outside of lib/libc/locale.  Use wchar_t.

The definition of this unused type meant we gratutiously differed from
standards compliant stddef.h/stdlib.h.
