Add check for deleted libs

To avoid issues like the one from RELEASE-587, every deletion directive like those:
https://github.com/nuxeo/nuxeo-dm-hotfixes/blob/release-9.10-HF04-1.0.0/src/main/resources/install.xml#L8

It is needed to:

1. download the full build from the nexus:
   org.nuxeo.ecm.distribution:nuxeo-server-tomcat:<VERSION>:zip
2. check every delete directive for the file not to be present in the HF full build. If it is then the test must fail.
