Subject: backend: Make sure to normalize paths before checking if it is a
 system dir
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Otherwise if we for some reason get '/usr/lib/../lib' in there
we end up saying it is not a system path.

And for some reason here I got:

```
$ pkg-config --libs libffi                                                                                                             148  ST 117   hotdoc
-L/usr/lib/../lib -lffi
```
