lkl: update dpdk version to 17.02 from 2.2

Browse Source 
We can't link with libdpdk.a (combined library) on circleci (Ubuntu
12.04) while okay on Fedora25.  So link necessary libraries instead.

Now dpdk also uses __attribute__((constructor)) in order to controle the
order of init function.  the hijack library accordingly changes the
order to be executed _after_ dpdk initialization.
