Limit is already increased for standard xorg plasma distribution to
start, but with wayland, even more libraries being added
Increasing this limit to 1 << 20 (1M) seems to be enough (For me
length is 80K), and not so much for regular desktops

start_kdeinit reads its environment over a pipe from start_kdeinit_wrapper. For
security, each environment entry must be smaller than 4kb by default. Qt-based
applications in Nixpkgs may have larger environments, and the recent upgrade to
Plasma 5.17 pushed start_kdeinit_wrapper over the limit. The limit is now
extended to 16kb.
This problem was not detected during testing because the failure is silent:
start_kdeinit will continue with an empty environment. In other circumstances,
this strategy might work, but it does not work on NixOS. This failure is now
treated as a fatal error.
Fixes: #79707
