Revert changes overriding rapids-cmake repo. (#1209)

PR #1177 was merged a little too early when CI passed due to the presence of a `/merge` comment and sufficient approvals. This reverts a temporary change to the rapids-cmake repo that is no longer needed because rapidsai/rapids-cmake#368 has been merged.
