build: create JSON files containing image info

The JSON info files contain details about the created firmware images
per device and are stored next to the created images.

The JSON files are stored as "$(IMAGE_PREFIX).json" and contain some
device/image meta data as well as a list of created firmware images.

An example of openwrt-ramips-rt305x-aztech_hw550-3g.json
