Subject: [PATCH] Add expectation for externally managed marker in x86-64 macOS
 system test (#16628)

This is failing with

```
Run python3 scripts/check_system_python.py --uv ./uv
INFO: Checking that `pylint` isn't installed.
WARNING: Package(s) not found: pylint
INFO: Installing the package `pylint`.

  To install Python packages system-wide, try brew install
  xyz, where xyz is the package you are trying to
  install.

  If you wish to install a Python library that isn't in Homebrew,
  use a virtual environment:

  python3 -m venv path/to/venv
  source path/to/venv/bin/activate
  python3 -m pip install xyz

  If you wish to install a Python application that isn't in Homebrew,
  it may be easiest to use 'pipx install xyz', which will manage a
  virtual environment for you. You can install pipx with

  brew install pipx

  You may restore the old behavior of pip by passing
  the '--break-system-packages' flag to pip, or by adding
  'break-system-packages = true' to your pip.conf file. The latter
  will permanently disable this error.

  If you disable this error, we STRONGLY recommend that you additionally
  pass the '--user' flag to pip, or set 'user = true' in your pip.conf
  file. Failure to do this can result in a broken Homebrew installation.

  Read more about this behavior here: <https://peps.python.org/pep-0668/>
