    ci: Run flatpak CI only for master
    
    The current flatpak scripts runs the job using the manifest,
    which retrieves and builds the source from git master. Therefore,
    it is unhelpful to build the MR.
    
    For the moment, we will build the flatpak module only for
    commits on master. Once we fix the script, we can extend the
    CI tests to run for MR as well.
