Fix various memory leaks.

The XML_ParserCreate_MM one was found by Florian Weimer in
https://bugzilla.redhat.com/show_bug.cgi?id=888728 .

This should cover everything found by valgrind on the JS authority
test, augmented with a call to
polkit_backend_authority_enumerate_actions() to verify the
XML_ParserCreate_MM case.
