    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.
