Wait for idle queue after submitting an empty job

The test below imports an external signaled semaphore and submits to the
queue an empty job that waits on that signaled sempahore, but the test
returns without any further wait, which means the external sempahore may
be destroyed before the driver has had a chance to use it.

Affected tests:
dEQP-VK.api.external.semaphore.sync_fd.import_signaled_temporary

Components: Vulkan
VK-GL-CTS issue: 3636
