Reviewed by Per Arne Vollan.

Telemetry has revealed a sysctl-read call that is needed in normal use:

    kern.willshutdown

We can also silence a few sysctl-read calls that are only needed for use
cases where WebKit does not run:

    sysctl.proc_translated
    vm.page_wire_count

We should add them to the sandbox to avoid spurious logging.
