Add lp64d symlink to parent directory on riscv64

On RISCV we typically expect to have /usr/lib64/<ABI> directory. Some
software is strict about it, and some actually fallback to /usr/lib64.

We only support a single ABI, that's lp64d. We have it as a symlink back
to the parent. That means /usr/lib64 and /usr/lib64/lpd64 both point to
the same content.
