daemontools: use u-a for /usr/bin/svc and /usr/bin/svok
* busybox provides the same, causing busybox postinst to fail when both packages
are installed in the same image:
update-alternatives: Error: not linking rootfs/usr/bin/svc to /usr/bin/busybox.nosuid since rootfs/usr/bin/svc exists and is not a link
update-alternatives: Error: not linking rootfs/usr/bin/svok to /usr/bin/busybox.nosuid since rootfs/usr/bin/svok exists and is not a link
