build: avoid generating JSON info on missing image

Previously, build would fail for targets containing devices with not
initramfs image (such as mpc85xx-p1010). Only generate the JSON image
info for the initramfs image when we have one to avoid breaking the
builds.

Fixes commit d3140d052964 ("build/json: generate json file for initramfs")
