The test programs are not build by default but we want at least the
build coverage, so add them. Also make the build parallel.

Rename the directory for continuous integration scripts to a more
generic name as we're going to use more than one. The base image on
travis has an old kernel. It's not possible to use a newer one and some
tests fail making the coverage unreliable.
