ec4391f4 - chore: downgrade warning to debug log on clonefile failure (#28637)

chore: downgrade warning to debug log on clonefile failure (#28637) Ref https://github.com/denoland/deno/issues/26928. This was originally a warning so potential bugs would be visible. Now that the code has been working for a while without issues, and since the warning can be triggered in a valid case (as in the issue above, where the warnings also hid the real diagnostic), let's downgrade this from a warning to a debug log.
