Title: Bugs/dont use cdpath

This creates `__rvm_cd` which doesn't respect CDPATH, but more or less leaves the variable alone otherwise.

It should fix #1375

Review would be good, I haven't tested it super thoroughly, I also considered

```bash
CDPATH="." buildin cd "$@"
```

but I didn't have access to enough shells to check that actually does what I'd expect with builtins.
