[PATCH 2/2] .travis.yml: Add kernel build deps for acceptance tests

[Wainer dos Santos Moschetta]

The tests/acceptance/pvh.py test builds the Linux kernel
at runtime so it needs dependencies installed in the
container. Current used container image misses only
libelf-dev, which is then added with this change.
