fix(3p/nix/repl): Scan NixRepl for GC roots r/1250
Backport of https://github.com/NixOS/nix/commit/b244e65cdbc2949af70bd539bf8f3bd2fa952d07 Fixes https://github.com/NixOS/nix/issues/3175 ------ Original fault description by puck: I suspect I found the issue: The Nix Command structs are stored on the heap (using ref<T>, a wrapper around std::shared_ptr<T>), which means that any pointers that the NixRepl struct contains are eligible to be reaped by the GC. This includes, but is not limited to, the Env pointer, which seems to cause most of the random segfaults, or random other values in the environment, which seems to be what @arianvp experienced too.
