OMR Jenkins: Request for changes to RISC-V agent

Summary

I'd like to ask for two changes to OMR RISC-V build agent (https://ci.eclipse.org/omr/computer/riscv-build1/, #5254 (closed)):

if possible, increase the core file size hard limit to at least 8192
if possible, install ccache package

As of now, OMR code dump test fails. I believe this is because core file size hard ulimit is set to zero. See below an excerpt https://ci.eclipse.org/omr/job/PullRequest-linux_riscv64/26/consoleFull (text-search for ulimit). I checked on my testing docker image (using podman in fact, if that matters) and when hard ulimit is set to zero, test fails, when set to 8192 it passes.

As for ccache, following change in https://github.com/eclipse-cbi/jiro-static-agents/blob/9ff5faa3dc1a08d8df020f723bec719271b1f810/releng/riscv/Dockerfile should do it:
