The old code used direct negation to convert negative numbers to
positive values, which caused undefined behavior when the input
was INT_MIN since -INT_MIN cannot be represented in signed int.
Use QtPrivate::qUnsignedAbs() instead, which safely handles all
signed integer values including INT_MIN without overflow.
Fixes: QTBUG-139635
Pick-to: 6.11 6.10 6.9 6.8
