Switch back to resolving symlinks for rbenv executable (#1439)

Browse source 
Considerations:

- `./libexec/rbenv` executable is the entrypoint to the program;

- BASH_SOURCE might be the path to a symlink that has activated `./libexec/rbenv`;

- We must resolve the symlink to learn where rbenv's libexec directory is;

- It's not guaranteed that rbenv commands will always remain directly under their own "libexec" directory, since a package maintainer can change that, e.g. rbenv commands are sometimes placed into `/usr/libexec/rbenv/*`;

- Resolving symlinks might fail and in that case we just assume rbenv project layout.
