IpSecService is going to be moved into ConnectivityService
module. So, NetdService won't be visible to IpSecService
since it is a hidden class.
NetdService.get(timeout) is a method that blocks for specified time
until INetd instance is available. In SystemServer IpSecService is
created after NetworkManagementService and NMS uses NetdService.get()
to get INetd instance which is a method that blocks until an INetd
instance is available. Thus, connectNativeNetdService can be removed
because NMS already waits for INetd instance is available so IpSecService
should be able to get INetd instance immediately.
