Add string support to nvramtool.

To add a string to your cmos.layout, you need to specify type 's':

#start     len       type    unused   name
416        512       s       0        boot_devices

With this patch you can do

$ nvramtool -w boot_devices="(hd0,0);(hd2,1);(hd3)"

And FILO will attempt to load a menu.lst from any of these devices in that
order.

The patch is not exactly pretty, but a cleaner solution might have resulted in
a complete rewrite of the tool, which I did not want.
