1. Fix zig_host_app on NixOS …

   That's a problem with the dynamic loader:
   https://discourse.nixos.org/t/no-such-file-of-directory-when-trying-to-execute-binary-file/6150
   
   When linking `libapp.so` with `host.zig`, zig puts in the binary the
   standard path for the dynamic loader on linux:
   `/lib64/ld-linux-x86-64.so.2`
   
   However in NixOS, that file is somewhere else in the nix store (see:
   https://nixos.wiki/wiki/Packaging/Binaries#The_Dynamic_Loader). Removing
   the `-target` switch makes zig uses the host target for linking and puts
   the right path to the dynamic loader in the resulting binary. As we want
   to execute that binary file in this test, it makes sense to use the
   default target anyway.
   
   Note that this is relevant for the creation of the binary only. For the
   creation of the object file, it doesn't really matter. But I removed the
   `-target` switch as well there for consistency.
   
   Fix roc-lang#4180
