[git commit master] tar compability modes for dpkg

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=820874ed3872877601ee95adc275bda215f2d320
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

I've found couple of deb files which require old tar compability modes
to be unpacked. This patch allows me to enable them for dpkg without
enabling tar.
