fix(lua): extra CR (\r) in nvim -l output #38048

Browse Source 
Problem:
`nvim -l` prints an extra `\r` to stdout:

    :=vim.system({'cmd', '/c',  "echo print(1) | nvim -l -"}, {}):wait()
    {
      code = 0,
      signal = 0,
      stderr = "1\r\r\n",
      stdout = ""
    }

Solution:
Check `headless_mode` in `msg_use_crlf`.
