wifi: Use public WifiP2pManager, WifiAwareManager objects

Using the AIDL object requires the usage IServiceManager.getService()
method.

Note: The RemoteException catch block in RttService (which is being removed)
is redundant since both the services are hosted on the same process
(i.e system_server).
