Ensure sync_fd tests use valid file descriptors

The external.*.sync_fd.* tests fail on some implementations
because vkGet*FdKHR may return -1 (meaning pre-signalled) instead
of a valid file descriptor.

Affects:

dEQP-VK.api.external.semaphore.sync_fd*
dEQP-VK.api.external.fence.sync_fd*

Components: Vulkan

VK-GL-CTS issue: 957
