env_dpdk: add spdk_env_dpdk_external_init() 



This function indicates whether DPDK was initialized
external to the SPDK env_dpdk library.

This can be used in cases where we need to implement
different behavior when DPDK is initialized outside
of SPDK - in that case certain flags that SPDK would
prefer may not have been specified.  This will
be used in the next patch.
