luci-mod-status: convert bytes into KB / MB / GB on progress bar

Currently on the system status page the the memory usage is shown in kB
only. If you have a system with 1 GB of Ram its hard to read the large
numbers. This automatically formats the byte numbers more human readable
into KB / MB / GB.
