[PATCH 6/6] .travis.yml: Do some more testing with Clang

[Thomas Huth]

We are doing a lot of cross-compilation tests with GCC in the gitlab-CI
already, so we could get some more test coverage by using Clang in the
Travis-CI instead. Thus let's switch two additional jobs to use Clang
for compilation.
