Subject: travis: Make it possible to build against a dpdk branch.

Rework the build script so that we can pass branches and tags.

With this, DPDK_VER can be passed as:
- a string starting with refs/ which is understood as a git reference.
  This triggers a git clone on DPDK_GIT (default value points to
  https://dpdk.org/git/dpdk) for a single branch pointing to this
  reference (to save some disk),
- else, any other string which is understood as an official release.
  This triggers a tarball download on dpdk.org.
