tests/docker: convert riscv64-cross to lcitool

We still need to base this on Debian Sid until riscv64 is promoted to
a release architecture (or another distro provides a full cross
compile target). We use the new qemu-minimal project description to
avoid bringing in all the extra dependencies because every extra
package is another chance for sid to fail.
