[staging] perl: 5.38.2 -> 5.40.0 (#333286)

After discussing on Matrix in the [#staging](https://matrix.to/#/#staging:nixos.org) room, I'm merging this as-is without waiting for changes to the `enableParallelBuilding = false;` line.

There are several in-the-wings PRs (one from @emilazy) that attempt to bring load-limit, which is a more sensible accounting of the work that a derivation is doing, into Nix itself. If and when that lands, we'll be able to just set `enableParallelBuilding = true;` again, without any specific casing around the `NIX_BUILD_CORES` stdenv variable.
