Remove the amqp package from azure-iot-sdk build

Remove the amqp package from azure-iot-sdk build

At the moment the yocto receipt for azure-iot-sdk does not include
amqp symbols in libiothub_client.so library. It has been done due to build issue.

In result the amqp related symbols in libiothub_client.so are not resolved.
As the amqp is not used by AGL (cloudproxy service) at the moment, it is disabled at all.
