fix mods directory for SUSE

added fastcgi template (based on packaged mod_fastcgi.conf)
This looks nicer to me

```
if node.platform == "suse"
  mod_conf = "#{node[:apache][:dir]}/conf.d/#{application_name}.conf"
else
  mod_conf = "#{node[:apache][:dir]}/mods-available/#{application_name}.conf"
end

define :apache_conf do
  template mod_conf do
    source "mods/#{params[:name]}.conf.erb"
    notifies :reload, resources(:service => "apache2")
    mode 0644
  end
end
```
