CI Jenkinsfile: narrow archived xml file set to TEST-*.xml
CI Jenkinsfile: narrow archived xml file set to TEST-*.xml

Mask used to be *.xml causing over-archiving of results.xml
from every tester with latest one remaining in archive,
which was misleading as it appears from different tests.
This file is not used for anything so leave it out.
