Do not erronously export 'openat' symbol from rtld.
The symbol leaked after r276630 since lib/libc/sys/openat.c defines versions for openat using .symver (version script cannot assign two versions to one symbol), and rtld uses openat. Instead, directly use __sys_openat(). Reported and tested by: antoine Sponsored by: The FreeBSD Foundation MFC after: 1 week
