copyfiles: add a way to relax the file system checking for hardlink
This is critical for transaction file, less for hardlink/copy clone as we are
about to do. Since `pure` build does not have a `getfstype` implementation this
would disable hardlink clone for all pure build. So we add a parameter to
control that extra check.
