Update dependency from cprice404/inifile to puppetlabs/inifile

Using this module as-is results in a nasty deprecation warning:

```
==> client: Warning: cprice404-inifile is deprecated; please update to puppetlabs-inifile
==> client: Warning: cprice404-inifile is deprecated; please update to puppetlabs-inifile
```

Update dependencies to use `puppetlabs/inifile` module as it appears that the module simply moved namespaces.
