.gitlab-ci.d/container-cross: Fix RISC-V container dependencies / stages

The "riscv64-debian-cross-container" job does not depend on any other
container job from the first stage, so we can move it to the first
stage, too.

The "riscv64-debian-test-cross-container" job needs the debian11
container, so we should add a proper "needs:" statement here.
