build: add linux/riscv64 builds

[mmoll]

Description

I'd like to include trivy also on RISC-V in the k3s build I'm working on.

Not directly related: If diskspace on build time is still a relevant problem, I think limiting the parallelism of goreleaser could help.

Hi @mmoll !

The closed PR you’re referring to already answers the question about adding new platforms to the Trivy build process.

Well, I built a release with a standard GH worker without problems: https://github.com/mmoll/trivy/actions/runs/22230099295/job/64307084839
