ramips: define common MikroTik RouterBOARD image recipe

All these devices share the exact same image format.

The usb3 kmod is added for the rbm11g, as the rbm11g has a mini-pcie
slot like its bigger sibling. The usb kmod is necessary for
usb-over-pcie support, which is mandatory for a lot of LTE modules.
