Allow system_server to trigger the kernel synchronize rcu with open and
close pf_key socket. This action was previously done by netd but now
it need to be done by system_server instead because the handling code in
netd are moved to mainline module which will be loaded by system_server
in JNI mode.
Note: the permission will be removed from netd once all bpf interactions
have moved out of netd.
