Fix latency for ACL test cases

JIRA: YARDSTICK-1460 Cores running "mode=lat" must be properly configured with a correct "lat pos" parameter. When this parameter is missing, PROX exits with an error message. When the "lat pos" parameter is missing for cores running "mode=gen", latency values are not written into the packets. Also fixed some typos, packet inline format, IP len and UDP len.
