xplist: Plug memory leak when converting PLIST_UID nodes to XML

In node_to_xml nodes of type PLIST_UID are temporarily converted
to a PLIST_DICT for an appropriate XML output. Therefore a PLIST_KEY
and a PLIST_UINT node is created and inserted into the PLIST_DICT
node. Upon completion, the child nodes of the PLIST_DICT node are
detached from the original node and freed, however the data of the
child nodes - the key string and the uint value - are not.
This commit fixes it.
