This one is fairly similar to `environment.enableDebugInfo`[1] (hence the name). It ensures that the `debug`-output of packages defined in `home.packages` is installed if available and ensures that `gdb`/`elfutils` find those symbols by adding `~/.nix-profile/lib/debug` to the `NIX_DEBUG_INFO_DIRS`[2] variable.
