Fresh module install creates blank menu item

This is the same bug found in xsendfile which was resolved and commited by marcoka.

Change:

function nginx_accel_redirect_menu_alter(&$items) {
  $items['system/files'] = array(
    'page callback' => 'nginx_accel_redirect_file_transfer',
    'page arguments' => array('private'),
    'access callback' => TRUE,
  );

To:

function nginx_accel_redirect_menu_alter(&$items) {
  $items['system/files'] = array(
    'page callback' => 'nginx_accel_redirect_file_transfer',
    'page arguments' => array('private'),
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );

Could you please commit this change to your module?

Thanks.
