dhcp-relay needs a fresh tarball of bind unpacked in ${S}, but this is
done by fetching the tarball to ${WORKDIR}, then in do_configure moving
it to ${S} and unpacking it.
If dhcp-relay is re-configured, the tarball no longer exists in ${WORKDIR}
so this fails. Copy instead of moving so rebuilds work.
Also don't rename the downloaded file to just bind.tar.gz as that can
cause probems if the version changes.
