[polari] build: Specify test dependencies

[Florian Müllner <fmuellner src gnome org>]

commit 0d406ac56179832cb4f708a96a8c6a3f0fcc6c58
Author: Florian Müllner <fmuellner gnome org>
Date:   Wed Apr 28 21:27:56 2021 +0200

    build: Specify test dependencies
    
    `meson test` no longer rebuilds all dependencies, so make sure the
    files that are tested actually exist.
