applications: Use SimpleNetDevice instead of PointToPoint
Build fails on Mac OS for me:

This is because the bulk-send-application-test-suite.cc is located in the applications module and makes use of the PointToPointHelper, but the applications module does not depend on the point-to-point module.
The suggested fix is to replace the PointToPointNetDevice with the SimpleNetDevice (the applications module depends on the network module).
