CopyFail for Python versions < 3.10

Os did not contain splice() before version 3.10. This version of copyFail uses ctypes to make the syscall between descriptors without a utilizing the splice wrapper.

Works on both older and current versions of python3.

Based on https://github.com/theori-io/copy-fail-CVE-2026-31431.
