test: gstreamer: Disable gstreamer registry forks
ASan needs to be loaded first before gstreamer is loaded. This was not possible, so verify_asan_link_order was disabled. Better way to tackle this issue was disabling forks on the gstreamer side. verify_asan_link_order=0 disables the check on ASan side which checks if ASan was loaded before any other shared objects. Since, gstreamer spawns a child helper process while building the registry, we needed to disable this check. But with gst_registry_fork_set_enabled() it is possible to disable spawning this child helper process, so this ensures that ASan is loaded before any other shared object is loaded.
