I am running Guix System with Sway
guix (GNU Guix) 33a80e111096b05af3d60576dfcb2d67099dc60e

Running `QT_QPA_PLATFORM=wayland pcmanfm-qt` results in failure to
launch and the following errors:

```
21:50:38.413|qt.qpa.plugin|W|Could not find the Qt platform plugin "wayland" in ""
21:50:38.413|default|F|This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

zsh: abort      QT_QPA_PLATFORM=wayland pcmanfm-qt
```

Due to this problem, I cannot set this env var for my whole profile or
many programs will break. This means they run with xwayland instead of
native wayland. I have run some of these same programs on another
distro (postmarketOS on a Pinebook Pro) and found they run in Sway.

I believe this is likely a packaging issue with qt stuff.

I believe the modern manifestation of this problem was #57742, now fixed
on the staging branch (see commit e4ef2db8fda85a469a6fc89bf3c46c9d7e8d44ea).
