[Cocoa] Silence telemetry on MSC_mach_wait_until
https://bugs.webkit.org/show_bug.cgi?id=228112
<rdar://problem/78965631>
Reviewed by Per Arne Vollan.
We are processing a lot of telemetry for MSC_mach_wait_until in cases where a block with failure is the correct behavior.
Silencing the warning to reduce CPU and network traffic related to generating and de-duping telemetry on this call.
