    CI: Refresh Ubuntu Xenial container as 16.04-x86_64
    
    Rework the container to be non-root, use heredocs for legibility, and use
    apt-get --no-install-recommends to keep the size down.
    
    Ubuntu Xenial has no ninja-build package, so can't build the QEMU referenced
    by Xen 4.16.  Therefore, drop the dependencies too.
    
    This saves ~500M:
    
      registry.gitlab.com/xen-project/xen/ubuntu    16.04-x86_64           698MB
      registry.gitlab.com/xen-project/xen/ubuntu    xenial                 
1.21GB
