Remove dib-buildimage-debian-ironic post job

I noticed that this job was failing [1].  It was added with
If9363bff535f9d1fc9692767ac9194923030cfe7 , but there doesn't seem to
be anything published for it [2].

This would have to be fixed by pip-installing dib as done with
I5950c772b380cab926fd707cfed25db219a96f62 , but as it seems unused,
let's just remove it.
