Title: Don't match return value when loading lager

Lager may already be loaded so don't match against 'ok'.

I ran into this issue trying to run riak test. Here was output from trying to manually run chkconfig:

```
# /root/yz-verify/rt/riak_yz/dev/dev1/bin/riak chkconfig
Error generating config with cuttlefish
```

That doesn't say anything useful so then I ran `riak config effective`

```
# /root/yz-verify/rt/riak_yz/dev/dev1/bin/riak config effective
escript: exception error: no match of right hand side value {error,
{already_loaded,lager}}
