test: fix allocUnsafe uninitialized buffer check
Fixes parallel/test-buffer-bindingobj-no-zerofill to properly check
that buffers created with Buffer.allocUnsafe()
are not zero-filled.
The test introduced in #11706 passes even if the buffer has been zero-filled and fails if none of the buffer values are zero.
