The "build-tci" job in our CI is running the pxe-test that requires
slirp. However, we are going to remove the slirp submodule from QEMU,
so we need to run the test in a container that provides libslirp from
the OS distribution.
Currently, the debian-all-test-cross container that is used for the
"build-tci" job is based on Debian 10 - which is not supported by
QEMU anymore and does not have libslirp as a system library. Thus we
really need to update the container to Debian 11 now to keep the
"build-tci" job working.
