integration: jUnit output from e2e

Processing node-e2e.log into jUnit format is insane, it's chock-full of
terminal escape codes.  They would either need to be scraped/removed or
disabled somehow.  Instead, take advantage of ``e2e.go --report-dir=``
option.  This will cause it to store native jUnit results in the
specified directory for later collection.  The jUnit results are also
needed for the google test grid.
