  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.

  Log Message:
  -----------
  travis: Combine kernel builds.

Single kernel build job takes ~3 minutes in average. Most of
this time takes VM spawning and initial configuration.
Combining these 24 jobs in 4 allows us to better utilize workers
and not waste time on spawning VMs.

Before:

    24 jobs * 3 minutes = 72 minutes
    72 minutes / 5 workers = 14.4 minutes / worker

After:

    4 jobs * 10 minutes = 40 minutes
    40 minutes / 4 workers = 10 minutes / worker
    + 1 free worker that able to run other jobs at the same time.

  travis: Drop OSX workarounds.

TravisCI currently uses xcode9.4 as a default image and it
it has good version of libtool out-of-the-box.
Removing these workarounds saves 4-6 minutes of OSX build.
