tests: Make the tests pass for Python < 3.8

Before Python 3.8, xml.dom.minidom sorted the attributes of an element
when writing it to a file, while later versions output the attributes
in the order they were created. Avoid these differences by sorting the
attributes for each element before comparing the generated manifests
with the expected ones.
