xcode: allow ICMP ping relay on macOS + iOS platforms (#12048)
Fixes tailscale/tailscale#10393
Fixes tailscale/corp#15412
Fixes tailscale/corp#19808

On Apple platforms, exit nodes and subnet routers have been unable to relay pings from Tailscale devices to non-Tailscale devices due to sandbox restrictions imposed on our network extensions by Apple. The sandbox prevented the code in netstack.go from spawning the `ping` process which we were using.

Replace that exec call with logic to send an ICMP echo request directly, which appears to work in userspace, and not trigger a sandbox violation in the syslog.
