ci: Enable partial components build-check on riscv

Since we have RISC-V builders available now, let's start with
`agent-ctl`, `trace-forwarder` and `genpolicy` components to run
build-checks on these `riscv-builder`s, and gradually add the rest
components when they are ready, to catch up with other architectures
eventually.

This workflow could be mannually triggered, `riscv-builder` will be the
default instance when that is the case.
