Handle denorm flush to negative zero in unpackhalf2x16 tests.

Whether input fp16 values are flushed to zero is implementation
dependent. However, negative denorm values can be flushed to negative
zero and the logic did not handle that case.

Affects: dEQP-VK.glsl.builtin.function.pack_unpack.unpackhalf2x16*
Component: Vulkan
VK-GL-CTS issue: 1341
