[libvirt] [PATCH 2/5] domainsnapshotxml2xmltest: Allow for better testing of snapshots

Until now the test was only testing redefinition of snapshot XMLs stored
in tests/domainsnapshotxml2xmlout. This patch adds new infrastructure to
allow testing of files that may differ and will allow to utilize files
in tests/domainsnapshotxml2xmlin as new tests too.
