Title: nixos: limit size of systemd journal to 256M by default

The systemd default is 10% of FS, which is IMHO way too much.
Perhaps that was the reason why simple look at tail of the logs
took reading hundreds of megabytes (for the single last log message to appear).

I only have negligible server experience -- any comments?
