This fix tries to fix the issue raised in 29486 where interrupted
`docker build` leaves some tmp files in `/var/lib/docker/tmp`.
With tmp file name prefixed with `/var/lib/docker/tmp/docker-builderXXXXXX`.
The reason for the issue is that in `MakeTarSumContext()`:
```
if err := chrootarchive.Untar(sum, root, nil); err != nil {
return nil, err
}
```
the `err` is shadowed and caused the clean up function in `defer func()`
not being called.
This fix fixes the issue.
This fix is tested manually, as was specified in 29486:
```
rm -rf /var/lib/docker/tmp
mkdir repro && cd repro
fallocate -l 300M bigfile
cat > Dockerfile <<EOF
FROM scratch
COPY ./bigfile /
EOF
docker build .
{Cancel}
ls -la /var/lib/docker/tmp
```
This fix fixes 29486.
