Fix ?? in Nix warning message

Browse source 
Nix sometimes outputs a warning message like this:

```
directory /nix does not exist; creating it by running ‘?? using sudo
```

... when it really meant to output something that looked like this:

```
directory /nix does not exist; creating it by running 'mkdir -m 0755 /nix && chown gabriel /nix' using sudo
```

The reason why is due to some bizarre behavior in Bash where it will translate anything of the form `$x’` to `??`, leading to the incorrect warning message.  I don't know what is the origin of this Bash behavior, but the easiest fix is to just use ASCII quotes instead of unicode quotes.
