fix(test): clip shift size to 31 bits on arm

[jvdd]

Fixes a bug in test_utils.rs on arm devices in the overflow test.

Left shift value should be clipped at 31 to avoid overflow when performing left-shift on arm - as usize on arm is 32-bits.
Note that this case actually never occurs (as we pass 1 << 25 when dealing with f32 values, but the clipping is necessary to compile the .unwrap_or)
