chore(nint): move from //users/sterni to //nix r/2833

Since //web/bubblegum depends on nint, we need to move it to a non user
directory to conform with the policy established via cl/3434.
Note that this likely doesn't mean greater stability (which isn't
really implied in depot anyways), since I still would like to use a more
elaborate calling convention to allow for additional useful features.

-# nint — Nix INTerpreter
-
-`nint` is a shebang compatible interpreter for nix. It is currently
-implemented as a fairly trivial wrapper around `nix-instantiate --eval`.
-It allows to run nix expressions as command line tools if they conform
-to the following calling convention:
-
-* Every nix script needs to evaluate to a function which takes an
-  attribute set as its single argument. Ideally a set pattern with
-  an ellipsis should be used. By default `nint` passes the following
-  arguments:
-
-  * `currentDir`: the current working directory as a nix path
-  * `argv`: a list of arguments to the invokation including the
-    program name at `builtins.head argv`.
-  * Extra arguments can be manually passed as described below.
-
-* The return value should always be a string (throwing is also okay)
-  which is printed to stdout by `nint`.
-
-## Usage
-
-```
-nint [ --arg ARG VALUE … ] script.nix [ ARGS … ]
-```
-
-Instead of `--arg`, `--argstr` can also be used. They both work
-like the flags of the same name for `nix-instantiate` and may
-be specified any number of times as long as they are passed
-*before* the nix expression to run.
-
-Below is a shebang which also passes `depot` as an argument
-(note the usage of `env -S` to get around the shebang limitation
-to two arguments).
-
-```nix
-#!/usr/bin/env -S nint --arg depot /path/to/depot
-```
-
-## Limitations
-
-* No side effects except for writing to `stdout`.
-
-* Output is not streaming, i. e. even if the output is incrementally
-  calculated, nothing will be printed until the full output is available.
-  With plain nix strings we can't do better anyways.
-
-* Limited error handling for the script, no way to set the exit code etc.
-
-Some of these limitations may be possible to address in the future by using
-an alternative nix interpreter and a more elaborate calling convention.
-
-## Example
-
-Below is a (very simple) implementation of a `ls(1)`-like program in nix:
-
-```nix
-#!/usr/bin/env nint
-{ currentDir, argv, ... }:
-
-let
-  lib = import <nixpkgs/lib>;
-
-  dirs =
-    let
-      args = builtins.tail argv;
-    in
-      if args == []
-      then [ currentDir ]
-      else args;
-
-  makeAbsolute = p:
-    if builtins.isPath p
-    then p
-    else if builtins.match "^/.*" p != null
-    then p
-    else "${toString currentDir}/${p}";
-in
-
-  lib.concatStringsSep "\n"
-    (lib.flatten
-      (builtins.map
-        (d: (builtins.attrNames (builtins.readDir (makeAbsolute d))))
-        dirs)) + "\n"
-```
