Update the gitignore files to ignore more build artifacts (#23791)

saiarcot895 · web-flow · commit 59a84f5dff3f · 2025-09-05T11:56:36.000-07:00
Why I did it
After doing a build, there is a long list of new untracked (but not ignored) files that are either downloaded/extracted source directories or generated files. This makes finding actual new files harder.

How I did it
Look at the untracked files list in two sonic-buildimage trees that I have where a build was done, and update the gitignore list based on that. Also create directory-specific gitignore lists where needed.
