Allow libremote-processor to be compiled without networking support

In such a case, libremote-processor becomes useless but still acts as if it was working correctly. This is an easy way to have a version of libparameter that does not embed any networking code, which is required in some case for security compliance reasons. This can be achieved by turning the NETWORKING option OFF when configuring the CMake project. Signed-off-by: David Wagner <[email protected]>
