[release-branch.go1.15] runtime: stop preemption during syscall.Exec on Darwin On current macOS versions a program that receives a signal during an execve can fail with a SIGILL signal. This appears to be a macOS kernel bug. It has been reported to Apple. This CL partially works around the problem by using execLock to not send preemption signals during execve. Of course some other stray signal could occur, but at least we can avoid exacerbating the problem. We can't simply disable signals, as that would mean that the exec'ed process would start with all signals blocked, which it likely does not expect.
