meson: fix build with case-sensitive store on Darwin

[reckenrode]

Description of changes

I run Darwin with a case-sensitive store because it’s offered as an option. Meson is the first thing that actually broke because of it. This patch corrects the casing of “foundation” references in some of the tests that expect to find it.

I did not run nixpkgs-review because this change causes a lot of rebuilds, but I did rebuild a number of packages as part of my work on #229786.

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• For non-Linux: Is sandbox = true set in nix.conf? (See Nix manual)
• Tested, as applicable:
  • NixOS test(s) (look inside nixos/tests)
  • and/or package tests
  • or, for functions and "core" functionality, tests in lib/tests or pkgs/test
  • made sure NixOS tests are linked to the relevant packages
• Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
• Tested basic functionality of all binary files (usually in ./result/bin/)
• 23.05 Release Notes (or backporting 22.11 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking
  • (Module updates) Added a release notes entry if the change is significant
  • (Module addition) Added a release notes entry if adding a new NixOS module
• Fits CONTRIBUTING.md.

Two basic questions:

1. The case-insensitve store use case will still be functioning?
2. Shouldn't this patch be sent to Meson developers, too?

As I have said before, I have no access to a Darwin machine.

The patch shouldn’t affect users on case-insensitive stores. All it does is change the casing of foundation to Foundation on a couple of tests. I have submitted a patch upstream as mesonbuild/meson#11820. I updated my PR here to use fetchpatch instead of including the patch in nixpkgs.

Shouldn't this patch be sent to Meson developers, too?

It is now merged upstream.
