Cycle detection in `nix repl` is simpler and more reliable	9926	8672

The cycle detection in nix repl, nix eval, builtins.trace, and everywhere else values are printed is now simpler and matches the cycle detection in nix-instantiate --eval output.

Before:

nix eval --expr 'let self = { inherit self; }; in self'
{ self = { self = «repeated»; }; }

After:

{ self = «repeated»; }
