Built-Using field has disappeared

[dann frazier]

I noticed that the Built-Using control field is no longer being generated for linux-modules-nvidia- packages... well, except for the aws ones, which still have it.

For example:

$ apt show linux-modules-nvidia-440-5.3.0-51-generic | grep Built-Using
Built-Using: nvidia-dkms-440 (= 440.59-0ubuntu0.19.10.2), nvidia-kernel-source-440 (= 440.59-0ubuntu0.19.10.2)
$ apt show linux-modules-nvidia-440-5.3.0-53-generic | grep Built-Using
$

I'm guessing this commit is why - but it's unclear from the commit message if it was intentional:
