crypto/zuc: add driver for ZUC library

Added new SW PMD which makes use of the libsso SW library,
which provides wireless algorithms ZUC EEA3 and EIA3
in software.

This PMD supports cipher-only, hash-only and chained operations
("cipher then hash" and "hash then cipher") of the following
algorithms:
- RTE_CRYPTO_SYM_CIPHER_ZUC_EEA3
- RTE_CRYPTO_SYM_AUTH_ZUC_EIA3

The ZUC hash and cipher algorithms, which are enabled
by this crypto PMD are implemented by Intel's libsso software
library.
