Before this change we were using the wrong variable to read the filename length from. This meant that very long filenames were not being truncated as intended. This problem was spotted by Wang Zhiwei on the forum in a code review. See: https://forum.rclone.org/t/why-use-c-remoteforcopy-instead-of-c-remote-to-check-length-in-copy-operation/45099
