  [Cocoa] Allow two syscalls found by sandbox telemetry

Reviewed by Per Arne Vollan.

Telemetry on iOS and macOS shows that we need to allow access to SYS_fsctl in
the Network process, and silence the SYS_crossarch_trap syscall in all sandboxes.
This was discussed with the larger security team, and the need confirmed with the
components that require these syscalls.
