Cleaner output if sections are empty
Even with a completely empty config we still get the following output:
root
sysinfo
load: 0.87/0.92/0.98
ram: 243/168/0
uptime: 1d 22:18:19
netdev
ping
file
shellcmd
With this patch the sections are skipped if there are no entries and the
command no sysinfo can be used to skip displaying the system
information.
