The ci/test-build script unconditionally downloads the latest devel
snapshot. This is not practical for local development. Add a conditional
check for a file named devel.tar.gz, either it's missing or empty, then
download.
The empty file is also considered because this allows to use a docker
image that does not support conditional contents, so a stub file is a
fallback.

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.
