Inform the user in case their USB stick is formatted with NTFS

See #13206 (closed).

For example:

When I start Tails installed on NTFS
Then I see an error message about it in the Greeter
And the Login button is disabled
When I select my preferred language in the Greeter
Then the error message is localized (like the rest of the Greeter's UI)
And the Login button remains disabled

But Tails seems to work fine on NTFS (except Tails Installer), so another option would be to tell people about that when trying to clone their Tails. See #13206-note_33.
