examples/l3fwd-acl: update MAC addresses

Browse Source 
Introduces two changes into l3fwd-acl behaviour to make
it behave in the same way as l3fwd:
- Add a command-line parameter to allow the user to specify the
  destination mac address for each ethernet port used.
- While forwarding the packet update source and destination mac
  addresses.

For example, consider a dual processor socket platform with 8 physical cores, where cores 0-7 and 16-23 appear on socket 0,
while cores 8-15 and 24-31 appear on socket 1.
