replace ioutil.WriteFile usage with Fsync and friends

[Crypt-iQ]

ioutil.WriteFile doesn't sync the data to disk, so any data written with this function can easily be lost. It's even possible that only partial writes happen. Issuing an Fsync is a better alternative. There aren't many call-sites that do this and I wasn't able to evaluate whether any of these were critical, but better to be safe than sorry.
