add support for 'netd_readonly'

For use by:
- maps netd should have read but not write access to
  (needed due to netd being root with DAC_OVERRIDE,
   and thus not obeying standard unix permissions)
- programs that netd should have access to but
  not netutils_wrappers (which due to being able to
  run iptables, needs access to xt_bpf programs)
