    tests/tcg: Fix building outside of the source tree

    Running TCG tests from a build directory that is outside of the source
    tree fails with:

        [...]/qemu/tests/tcg/multiarch/libs/float_helpers.c:228:1: fatal error: opening dependency file tests/tcg/s390x-linux-user-float_convs.d: No such file or directory

    This is because the build directory is not mounted into the container.
    Add this mount. Do not bother with preventing overlapping mounts, they
    are harmless.

    Fixes: 27939ad414ca ("tests/tcg/meson.build: introduce cc_dockerfile and cc_docker_host_arch")
