Reduce number of link jobs in ubuntu debug build (#10671)

Summary:
For some reason the linux debug build has started to fail because it get's oom killed during linking: https://github.com/facebookincubator/velox/actions/runs/10259255187/job/28383420958#step:7:6891

I am not sure if the addition of parquet in #10648 is to blame, in that PR the job did not fail.
