    [SPARK-35463][BUILD][FOLLOWUP] Redirect output for skipping checksum check
    
    ### What changes were proposed in this pull request?
    
    This patch is a followup of SPARK-35463. In SPARK-35463, we output a message to stdout and now we redirect it to stderr.
    
    ### Why are the changes needed?
    
    All `echo` statements in `build/mvn` should redirect to stderr if it is not followed by `exit`. It is because we use `build/mvn` to get stdout output by other scripts. If we don't redirect it, we can get invalid output, e.g. got "Skipping checksum because shasum is not installed." as `commons-cli` version.
    
    ### Does this PR introduce _any_ user-facing change?
    
    No. Dev only.
    
    ### How was this patch tested?
    
    Manually test on internal system.
    
    Closes #32637 from viirya/fix-build.
