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.
