coreutils: Backport fix for lseek_copy loop

coreutils: Backport fix for lseek_copy loop

We've seen intermittent failures on the autobuilder related to creating
hddimg images after updating to coreutils 9.9. The error message seen
is:

  install: cannot lseek '.../core-image-minimal/1.0/sources/core-image-minimal-1.0/hddimg/rootfs.img': Invalid argument

This corresponds to an invalid argument passed to lseek() in the
create_hole() function in src/copy-file-data.c in coreutils. This in
turn is being given bad arguments due to incorrect handling of loop
variables in lseek_copy().

The upstream bug report [1] refers to an infinite loop, which isn't
quite what we're seeing, but the cause is likely the same. So, we're
applying the upstream fixes.
