Verify that eglClientWaitSyncKHR() correctly handles zero timeout before
and after the sw sync fence is signaled.

+/**
+ * Verify that eglClientWaitSyncKHR() correctly handles zero timeout before and
+ * after sw_sync_timeline_inc().
+ *
+ * From the EGL_KHR_fence_sync:
+ *
+ *     If the value of <timeout> is zero, then eglClientWaitSyncKHR simply
+ *     tests the current status of <sync>.
+ *
+ *     [...]
+ *
+ *     eglClientWaitSyncKHR returns one of three status values describing
+ *     the reason for returning. A return value of EGL_TIMEOUT_EXPIRED_KHR
+ *     indicates that the specified timeout period expired before <sync>
+ *     was signaled. A return value of EGL_CONDITION_SATISFIED_KHR
+ *     indicates that <sync> was signaled before the timeout expired, which
+ *     includes the case when <sync> was already signaled when
+ *     eglClientWaitSyncKHR was called. If an error occurs then an error is
+ *     generated and EGL_FALSE is returned.
