Link nvinfer_pluing as a static library instead of dynamic. This will

reduce some of the headache with how TensorRT installs on the system as
well as make the install experience with end users of the library a little
bit smoother.

Ideally we would like to statically link all of the TensorRT libraries but
that doesn't seem possible at this stage due to protobuf symobls not being
found in the static version of nvinfer and nvparsers. This seems to be a
bug in the binary releases of these artifacts.
