mac-virtualcam: Fix random crashes in applications loading VirtualCam

Browse Source 
Without invalidating the mach port used for sharing the IOSurface
between OBS and the application displaying the virtual camera output,
IOKit seems to run into the issue of receiving "shared" mach ports,
possibly because of port exhaustion. IOKit requires a "new" port
however and crashes upon that error otherwise.
