hurd: fix build with -fstack-protector-strong
libmachuser and libhurduser also need stack_chk_fail_local and they do not
link against libc_nonshared.

       * mach/stack_chk_fail_local.c: New file.
       * hurd/stack_chk_fail_local.c: New file.
       * mach/Machrules ($(interface-library)-routines): Add
       stack_chk_fail_local.
       * mach/Versions (GLIBC_2.4): Add __stack_chk_fail.
       * hurd/Versions (GLIBC_2.4): Add __stack_chk_fail.
