Add initial Travis CI support

This runs "make distcheck" using gcc-9, gcc-8, gcc-7, and clang
on x86_64, x86, x32, aarch64, s390x, and ppc64le architectures.

* .travis.yml: New file.
* ci/install-dependencies.sh: Likewise.
* ci/run-build-and-tests.sh: Likewise.

Resolves: https://github.com/linux-pam/linux-pam/issues/28
