Option to mount boot media read-only

When having CF or USB install, it would be nice to have an option to mount /media/usb or /media/sda1 as read-only. This would also need support from lbu to remount the media as read-write when committing config changes (and remount back to ro).

This adds a bit of security (action needed to make things writable), and also hard reboot tolerance (the media is ro, so someone cutting powers off unexpectedly will have zero possibility to corrupt media).
