Subject: Do not symlink a symlink in mkrc

We have a bug when calling mkrc(1) on a symlink:

```sh
mkrc ~/.vimrc # links ~/.vimrc to ~/.dotfiles/vimrc
mkrc ~/.vimrc # deletes ~/.dotfiles/vimrc
```

This catches that case ahead of time, preventing the user from running
mkrc(1) on a symlink.

Fix #144.
