Elliott Hughes 6660d6c00b Rewrite renameat().
risc-v doesn't have renameat(2), only renameat2(2). Similar to other
architectures, let's make sure everyone's on the same code path by
having all implementations of renameat() go via renameat2().

I've also moved the existing rename()-in-terms-of-renameat() to be in
terms of renameat2() to cut out the middleman!
