No wic image for m3-nogfx

Please close when done.

I assume only the template did not catch-up . So let's bring nogfx to the same state.-

The only image build for m3ulcb is m3ulcb-nogfx, and is the only image without sd wic file (except qemux86-64).

It will be nice to have, at least, one image usable on m3 board.

If m3ulcb-nogfx is not a good choose,  perhaps having a telematics image for m3 board user will be a good idea?

Thats expected as the m3ulcb-nogfx target is for CI use and we only need the .ext4 for CI . Who wants the limited image for sd ?
