Process lists correctly

Creates multiple value_of elements within a single yamlfilecontent_item
element instead of creating multiple yamlfilecontent_item elements
containing single value_of elements. According to the schema proposal
the value_of element can occur 0 to unbounded times. Also, this behavior
is consistent with xmlfilecontent probe.
