Add renameat2 function [BZ #17662]
The implementation falls back to renameat if renameat2 is not available in the kernel (or in the kernel headers) and the flags argument is zero. Without kernel support, a non-zero argument returns EINVAL, not ENOSYS. This mirrors what the kernel does for invalid renameat2 flags.
