Use DCA custom filter parameter for fields in filter menu

DCA parameter `['list']['sorting']['filter']` must also be used in filter menu for fields.

For example, for next parameter:

```php
<?php
$GLOBALS['TL_DCA']['tl_TABLE']['list']['sorting']['filter'] = array(
   array('status >= ?', 5)
);
```
there could be a situation when filter menu shows field values that can be only available for `status < 5` and this is wrong.
