Convert chown() failure to a warning in tar(1)

This particular change does not have any immediate shortcomings.
We still print a warning to alert the user.

Exiting on a chown() failure caused problems when untarring
inside a restricted user namespace on Linux where the uid/gid
mappings were limited.
