Yiwei Zhang a861f9a0b2 zink: fix zink_create_fence_fd to properly import
This change fixes below:
1. Dup the fence fd, otherwise, since external semaphore import takes
   the ownership of the fd, non-Vulkan part touches the fd leading to
   undefined behavior. This can be hit on implementations that defer
   the processing of the passed fd.
2. Use VK_SEMAPHORE_IMPORT_TEMPORARY_BIT for importing since that's
   required for SYNC_FD handle type because of its copy transference.
   Meanwhile, doing temporary import for opaque fd is fine in this path.

Fixes: 32597e116d ("zink: implement GL semaphores")
