copy_file: fix progress bar for files larger than 2G

Files larger than 2G cause the benign bug, that the progress bar is no
longer accurate. Use loff_t to fix this.

Note that printed % HASHES_PER_LINE in show_progress implies a 64-bit
division. A previous commit changed the constant divisor to a power of
two, so a division shouldn't be generated. The original multiplication
and modulo operations are left as is for clarity.
