Is systemd itself setting up the /run tmpfs or have you got libvirt
doing that ? If the former, you can can switch to making libvirt do
it and then add in the dbus mount too eg something like this:

  <filesystem type="ram">
     <source usage="1024"/>
     <target dir="/run"/>
  </filesystem>
  <filesystem type="mount">
     <source dir="/run/dbus"/>
     <target dir="/run/dbus"/>
  </filesystem>


Alternatively just use a single mount

  <filesystem type="mount">
     <source dir="/run/dbus"/>
     <target dir="/some/where/else"/>
  </filesystem>

and then inside the container startup do  'mount --bind /some/where/else /run/dbus"
