Liblastfm doesn't compile with http-conduit < 1.9

Fails to compile with old versions of http-conduit.

```
src/Network/Lastfm/Response.hs:60:16:
    Couldn't match expected type `C.CookieJar -> e0'
                with actual type `C.HttpException'
    The function `C.StatusCodeException' is applied to three arguments,
   but its type `C.Status -> C.ResponseHeaders -> C.HttpException'
   has only two
```
