psychon e51189ea43 Get rid of znc.conf-backup ...

The old code created a copy of the config file before writing a new version.
This backup is now gone.

With this patch the config is written to a temporary file znc.conf~ and then
fsync()d to make sure the data safely is on the disk. Then the real config file
znc.conf is overwritten with this temporary file via a rename() call.

This should be safer than the old way, plus it gets rid of a unneeded file.
