Wrong name in zabbix::userparameters resource example.

Hi Werner,

Both $source  and  $content file resources in [userparameters.pp] (https://github.com/karolisc/puppet-zabbix/blob/master/manifests/userparameters.pp)
has this  -  **file { "${include_dir}/${name}.conf":**

Leaving mysql.conf will add extra "conf" to the file name.
