[PATCH RESEND 3/3] .travis.yml: Test building with Xcode 11.3

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

We currently run a CI job on macOS Mojave with Xcode 10.

QEMU policy is to support the two last major OS releases.
Add a job building on macOS Catalina, which comes with Xcode 11.

Split the target list in two, as we don't need to cover twice the
same targets.
