[Buildroot] systemd-timesyncd doesn't start with default config and skeleton

Zoltan, All,

On 2016-08-22 10:41 +0200, Zoltan Gyarmati spake thusly:

The best solution is that I get to finish my skeleton-revamp series and
get it merged( first was submitted on the lkist, second is WIP taking
into account the comments that were made on the first):
    https://git.buildroot.org/~ymorin/git/buildroot/log/?h=yem/systemd-skeleton
    https://git.buildroot.org/~ymorin/git/buildroot/log/?h=yem/systemd-skeleton-2

Unfortunately, that won't be in 2016.08, as I haven't had time to finish
it properly before rc1. So it will only go in for next cycle... :-/

In the meantime, just use a post-build script that cleans up the mess,
like tweaking the unit file to not require PrivateTmp, or to remove the
/var/tmp symlink and make it a directory.
