Subject: [PATCH] Remove cargo home chown steps

The Linux runner images give the runner user ownership of /opt/cargo
since https://github.com/azure-management-and-platforms/hyperlight-ci-dev-images/pull/13.
The tart arm64 runners have no /opt/cargo. The step still walks the
whole directory, taking 10 to 40 seconds per job.
