build(debian): Avoid spamming .gitconfig with the same safe directory in local build

[EduardGomezEscandell]

Not cool:

[safe]
        directory = C:/tools/flutter-base-dir
        directory = /mnt/c/Users/edu19/Work/ubuntu-pro-for-windows
        directory = /mnt/c/Users/edu19/Work/ubuntu-pro-for-windows
        directory = /mnt/c/Users/edu19/Work/ubuntu-pro-for-windows
        directory = /mnt/c/Users/edu19/Work/ubuntu-pro-for-windows
        ...

More is better though, no? :)

Ok, even if there is no safe.directory entry, it will return 1 and then head to ||.

Totally on purpose 😅
