This follows up on commit 98666c8afc,
which did the same for QString. If someone wants to get formatting
suitable to an unsigned value, they can cast the value to that
unsigned type and the correct overload shall pick it up.
[ChangeLog][Important Behavior Changes] QByteArray's formatting of
negative whole numbers to bases other than ten now, like QString's
(since Qt 6.0), formats the absolute value and prepends a minus sign.
Task-number: QTBUG-53706
Pick-to: 6.2
