Fixed Network Preferences on Big Sur

[ErrorErrorError]

Hey!

Just a minor fix with Network Preferences not looking like a preference panel for devices >= 11.0. This is how it looked like before:

After with this fix:

Edit: Also improved with the logging system for devices >= macOS 11.0. For itlwm, I added https://openintelwireless.github.io/itlwm/Troubleshooting.html#using-dmesg so the user can extract itlwm since Big Sur does not load logs from bootloader using the log command.

Ready for review!

Well done!

The Prefs Window looks perfect, the code for that part looks good as well.

We might need to inform the users about the issues during the log generation process, especially the one that asks users to add msgbuf and use dmesg. I think we could show an alert with Error occurred while generating bug report as the message and append the errors to informativeText.

Maybe checking the existence of msgbuf in boot-args and then generate proper logs would be a better approach?

Sounds like thats a better approach to me. We can also ask the user to input their credentials kind of how I have it so it can show the user's stored wifi password but instead for dmesg, but well that's just an idea for now.

Feel free to add/improve on script execution. Couldn't manage to call dmesg without asking for permission to the user, and being able to change the text of the alert. The good thing it only asks for devices >= macOS 11.0
