We already build and cache with nix, no need to waste time doing it in ansible. Closes PSQL-1457
Nothing uses is in tree or internally, also why were even we *building* nginx? Closes PSQL-1632
No longer building anything in ansible and these are no longer installed so do not need this cleanup.
Mostly so we have one less nixpkgs fetched/copied into the store for builds, but its seems like there might be some perf improvements to n-e-j too.
Lets avoid a whole other nixpkgs source fetch/copy + all of the runtime dependencies that bloat the image (glibc + w/e else). Instead lets just define these packages so we share everything.

What kind of change does this PR introduce?
Feature
What is the current behavior?
We have 3 copies of nixpkgs in our flake, 2 are used in our outputs and the other is for nix-eval-jobs.
What is the new behavior?
Only one nixpkgs.
Additional context
Dropping unnecessary nixpkgs is nice for a few reasons the most obvious is less needs to be fetch and copied into the store at build time so has some benefits there. The big benefit is in dropping nixpkgs-oldstable which was used for curl v8.6 and v8, but that also ends up "duplicating" all the dependencies (libc + others) with the rest of the tree. Nix handles that fine but bloats our final image. Instead of whole nixpkgs and deps we can just build those old packages on our new nixpkgs and get the functionality without the bloat.
