[PATCH 15/12] CI: Refresh Ubuntu Xenial container as 16.04-x86_64



Rework the container to be non-root, use heredocs for legibility, and use 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           700MB
  registry.gitlab.com/xen-project/xen/ubuntu    xenial                 1.21GB
