Install qemu-user-static on some dockerhosts

[sxa]

RISC-V is currently building in an emulated docker container on x64 hosts. With the RISE system being decomissioned the other system I had with this is dockerhost-azure-ubuntu2204-x64-1 which had qemu-user-static installed and had the qemustatic label applied so it can be used for builds. We should probably look at having more machines configured like this. Noting that this needs the version from Ubuntu 22.04 or later, so it should NOT be set up on Ubuntu 20.04 dockerhost systems.

Note: This has been done on the Azure x64 Ubuntu 20.04 dockerhost, but it should get added intot he playbooks for follow-on deployments (particularly with Ubuntu 24.04 systems, since that has a version out of the box that will support building JDK11/riscv64 in a container.

Related to #3585 as we would like to run these only on Ubuntu 24.04 hosts to get the latest qemu (instead of installing a separate qemu which isn't from the standard distribution repositories)
It is believed that the qemu version is related to the failure to build JDK11/riscv64 although the most recent failures appear independent of this.

JDK11/riscv64 enviroment on an Ubuntu 24.04 host is now working, therefore closing. We can add additional systems with the qemustatic if necessary in the future
