    hurd: Fix __close_nocancel_nostatus availability
    
    Not only libc/rtld use __close_nocancel_nostatus.
    
    * sysdeps/mach/hurd/Makefile [$(subdir) == io] (sysdep_routines): Add
    close_nocancel_nostatus.
    * sysdeps/mach/hurd/Versions (libc): Add __close_nocancel_nostatus to
    GLIBC_PRIVATE.
    * sysdeps/mach/hurd/not-cancel.h (__close_nocancel_nostatus): Declare
    function instead of defining inline.
    [IS_IN (libc) || IS_IN (rtld)] (__close_nocancel_nostatus): Make
    function hidden.
    * sysdeps/mach/hurd/close_nocancel_nostatus.c: New file.
