modules/filetype: ensure that the module does not set empty settings

Browse source 
When setting any filetype suboption to null (or anything else guarded by
mkIf) it's value becomes:

    { extension = null; filename = null; pattern = null; }

Account for that case in mkIf condition so that the option would not
produce empty filetype definition.
