nixos/tests/{sway,cage,cagebreak}: Fix the tests on aarch64-linux
Since the update to wlroots 0.13 (e03dde82a7) the default VGA card
isn't supported anymore and we needed to switch to virtio (qxl didn't
work either). However, as it turned out "-vga virtio" (28b8cff301)
broke the test on AArch64. Luckily there's a third option that works on
all three supported platforms: virtio-gpu-pci

According to [0] "This device lacks VGA compatibility mode but is
otherwise identical to the virtio vga device. UEFI firmware can handle
this, and if your guests has drivers too you can use this instead of
virtio-vga. This will reduce the attack surface (no complex VGA
emulation support) and reduce the memory footprint by 8 MB (no pci
memory bar for VGA compatibility). This device can be placed in a PCI
Express slot."
So in the end this seems like the ideal choice :)

nixos/tests/cagebreak: use wayland-info instead of wallutils
wayland-info from wayland-utils is already used in other Wayland
tests whereas wallutils' wayinfo is not.

nixos/tests/cagebreak: Fix the test
Starting Cagebreak as X11 client doesn't work anymore as wlroots 0.13
started to require the DRI3 extension which isn't supported by LLVMpipe:
machine # [   13.508284] xsession[938]: 00:00:00.003 [ERROR] [backend/x11/backend.c:433] X11 does not support DRI3 extension

The test broke after updating Cagebreak in #121652 (bf8679ba94).

XWayland still fails for unknown reasons:
Modifiers specified, but DRI is too old
libEGL warning: DRI2: failed to create dri screen
libEGL warning: NEEDS EXTENSION: falling back to kms_swrast
glamor: No eglstream capable devices found
glamor: 'wl_drm' not supported
Missing Wayland requirements for glamor GBM backend
Missing Wayland requirements for glamor EGLStream backend
Failed to initialize glamor, falling back to sw

/nix/store/kcm3x8695fgycf31grzl9fy5gggwpram-xterm-367/bin/xterm: Xt

The fallback to software rendering is to be expected but it looks like
XWayland is crashing with "failed to write to XWayland fd: Broken pipe".

25bef2d8f9 treewide: simplify pkgs.stdenv.lib -> pkgs.lib
The library does not depend on stdenv, that `stdenv` exposes `lib` is
an artifact of the ancient origins of nixpkgs.
