nixos/getty: add services.getty.loginOptions
This corresponds to agetty's --login-options argument. With this change, I can set services.getty.autologinUser = "qyliss"; services.getty.loginOptions = "-- \\u"; and have my username prefilled, but with my password still required (unlike the normal autologinUser behaviour).
