Should wait until time is synced, still uses legacy sysv-init

[Iiro Laiho]

In order to run aiccu, we need following prerequisites:

- Network should be connected
- Time should be synced

Aiccu does not retry when it fails to connect to network. This can be a problem with laptops that connect to network via WLAN. That is by design to reduce load caused to SiXXs' servers by misconfigured clients, see following Arch's and Fedora's bug reports:

https://bugs.archlinux.org/task/38221
https://bugzilla.redhat.com/show_bug.cgi?id=844607

Perhaps we should write a systemd service file for aiccu and wait until time-sync.target. Another, possibly better, way is to completely ditch aiccu's service and let network-manager handle starting it.

EDIT: Aiccu should handle network changes, so waiting until time-sync should be the correct way to do this if I understand right.

aiccu package should be taken out of distribution due to closing of sixxs.net - there is no running tunnel broker any more.
