travis: Cache DPDK build.
This change enables cache for DPDK build directory, so we'll never
build same version of DPDK again. This speeds up each DPDK related
job by 4-6 minutes effectively saving 30-50 minutes of the total time.
Ex. Full TravisCI run on 'trusty' images:
Without cache:
Ran for 1 hr 9 min 29 sec
Total time 4 hrs 55 min 13 sec
With populated cache:
Ran for 1 hr 2 min 18 sec
Total time 4 hrs 20 min 9 sec
Saved:
Real time: ~7 minutes.
Total worker time: ~35 minutes.
