By default stdenv strips all unused rpaths, but we use a few libraries
that are `dlopen`'d so we need to stop it from removing those. The
[`dontPatchELF`
flag](https://ryantm.github.io/nixpkgs/stdenv/stdenv/#var-stdenv-dontPatchELF)
disables that and makes the nix build work on wayland again.

Fix #26905
Close #26864
