scripts/package: tar-pkg: use tar --owner=root
Use the --owner= and --group= options to make sure the entries in
the built tar file are owned by root. Without this change, a
careless sysadmin using the tar-pkg target can easily end up
installing a kernel that is writable by the unprivileged user
account used to build the kernel.
Test that these options are understood before using them so that
non-GNU versions of tar can still be used if the operator is
appropriately cautious.
