[PATCH v2] MAINTAINERS: add myself as Continuous Integration maintainer

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

I have contributed all the ARM tests to gitlab-ci. After checking with
Doug, I am happy to volunteer to co-maintain Continuous Integration.

Also take the opportunity to remove the stale travis-ci entries.
