    tests/docker: fix ccache directory variable expansion

    DOCKER_QEMU_CCACHE_DIR is missing $() around DOCKER_QEMU_CACHE_DIR, so
    $HOME/.cache/qemu is never created.  podman then fails to mount it:

      Error: statfs /home/user/.cache/qemu: no such file or directory

    It only works if the directory already exists.  Add the missing $().

    Fixes: 8a1975e4d44b ("tests/docker: expose $HOME/.cache/qemu as docker volume")
