tests: remove func.sync.semaphore-fd.opaque-fd

This tests is not valid because it relies on implementation specific details.

When queueing an operations into a VkQueue, the semaphores operations associated with a given VkSubmitInfo are going to be executed at a given point in that over which the application has no control (this depends on how the implementation processes operations in the queue). That means that for a semaphore to be signaled/waited/signaled/etc... multiple time we need external synchronization to ensure that a wait applies to a particular signal operations.

This test was queueing many wait/signal operations on the same semaphore without any synchronization between them, leading to undefined behavior.
