[PATCH] examples/ipsec-secgw: add security capabilities mapping

[Akhil Goyal]

Currently the cryptodev queue pair mapping was done only
on lookaside crypto capabilities.
But device capabilities for lookaside crypto and
lookaside proto may be different.
Hence, mappings are also added for rte_security_capabilities
of cryptodev.
