The free tier of travis-ci has ended on 05/2021, remove the scripts.
Nowadays zstd has made it to all distros so we don't need to build
it from sources, reiserfs support is fading out so we don't need to
build it either. The integration with coverity scan needs to be done
again. The rest has been moved to new github actions CI.

The free travis-ci.org service is going to be discontinued. The
replacement travis-ci.com could be used instead but is not exactly the
same.
The images provided by the service contained old kernel and this hinders
testing of new features, tests were failing and the coverage was
incomplete. The docker images will be used to do build coverage in
another way. A hosted CI is still desired so the search continues.
