vpp_lite: add cpu pinning support (VPP-467)
Proper cpu pinning in vpp_lite platform, like in normal vpp image.
Extended “show threads” command to show propper information.
Changed handling of coreID and socketID for threads in "show threads"
CLI, pthread_getaffinity is used instead of info stored in DPDK.
