While it isn't clear why this patch helps, it doesn't seem to have any negative
effects, so let's include it for now...

Otherwise, telnet login is allowed by default when neither a password nor SSH
keys are configured.

This significantly improves fastd performance, to the level it was before
Barrier Breaker.

This gets us an up-to-date alfred (and batman-adv 2014.x, as soon as we start to
support it).

The only packages we use from this repo are haveged and (now) fastd and its
dependencies, so we can make the switch safely without updating OpenWrt itself
to Barrier Breaker yet.

This now includes the previously added patch.
