Bugfix: network_utilization: parse error

JIRA: YARDSTICK-586

When run tc072, there is a bug: network_utilization: parse error, see the log:
ERROR ('network_utilization: parse error', [], [u'05:10:46', u'IFACE',
        u'rxpck/s', u'txpck/s', u'rxkB/s', u'txkB/s', u'rxcmp/s',
        u'txcmp/s', u'rxmcst/s', u'%ifutil'])

Maybe the tool has some changes.
