Description

I'm compiling the source code for Arch linux (CachyOS) but when i run it, it always throws back an error during the locale setup, i don't know if it's something specific to my distro, but i think there is an error somewhere.

I don't program on python, but reading the code, checking online and trying to use some common sense i figured out maybe on the line where you get the locale instead of:
locale_info = locale.getlocale(locale.LC_ALL)

you actually meant:
locale_info = locale.getlocale(locale.LC_CTYPE)

Because "LC_ALL" as far as i know is meant to be empty by default...

Steps to Reproduce

1. Clone repo
2. Compile in linux for linux briefcase build linux -u
3. Run the build briefcase run linux

Expected Behavior

It gives an error on startup when trying to get the users system language from LC_ALL which is the wrong system variable.

Actual Behavior

It should get the user's system language from LC_CTYPE instead of LC_ALL.
