tools/thermal/tmon: Fix signed shift UB in binding display
In the thermal zone binding display loop, the expression `(1 << j)`
performs a signed integer shift. When j reaches 31, this sets the
sign bit of a 32-bit signed integer, which is undefined behavior.
Fix it by using `(1U << j)` to perform an unsigned shift.
