mir,mir_2_15: Fix builds, modernise & fix VM tests

[OPNA2608]

1st:

mir and mir_2_15 currently fail on master, for different reasons.

• mir: Borked test
• mir_2_15: Borked test + glog dropped pkg-config generation + new glog version errors out when used: glog: disable broken test #371915 (comment)

Fix these builds, to unblock Mir-based compositors (Miriway & miracle-wm) and the Lomiri DE.

2nd:

Additionally, Alacritty, when launched in the VM tests, complains about the YAML config format:

machine # [   24.987840] miriway[1098]: [0.004055543s] [WARN ] [alacritty] YAML config "/etc/xdg/alacritty/alacritty.yml" is deprecated, please migrate to TOML using `alacritty migrate`

A lib.generators.toTOML was rejected in the past, so switch to pkgs.formats.yaml. For consistency, switch the INI file generation to pkgs.formats.ini as well.

3rd:

OfBorg fails to run the VM tests. Try some things to hopefully resolve this.

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin

• For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
  • sandbox = relaxed
  • sandbox = true
• 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/)
• 25.05 Release Notes (or backporting 24.11 and 25.05 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking

@lucasew nixpkgs-review doesn't run VM tests, so that isn't useful here. Please build nixosTests.miracle-wm and nixosTests.miriway if you want to give a meaningful review of this PR.

That's what I did

That's what I did

Then I would've expected your nixpkgs-review results to actually state that, like it does for me. Or at least a note stating that you did run them, in case your nixpkgs-review - for whatever reason - doesn't state it.

x86_64-linux

✅ 2 tests built:

• nixosTests.miracle-wm
• nixosTests.miriway

---

And while this output claims that the tests built successfully, they actually both failed… In a way that looks like something broke somewhere else. 😕

Edit: Issue should be fixed now (#375091), but still dumb that this is treated as a success in the review.

lomiri.lomiri has dependencies that are FTBFS on master, lomiri.lomiri-session depends on lomiri.lomiri. Going ahead with merging this already, since it's blocking running reviews for most Lomiri packages.
