Subject: [PATCH] prow.sh: publish individual JUnit files as separate artifacts

"junit/steps/junit_*.xml" contains the summary JUnit file of each step (sanity,
make_test, etc.). The original files as written by the e2e.test binary are
under "junit/<name>" where name is "parallel", "serial", etc.

This makes it possible to look up information that might get lost during the
transformation with filter-junit.go and debug that command.
