crypto: testmgr - Add ansi_cprng test vectors

Add ANSI X9.31 Continuous Pseudo-Random Number Generator (AES mode),
aka 'ansi_cprng' test vectors, taken from Appendix B.2.9 and B.2.10
of the NIST RNGVS document, found here:
    http://csrc.nist.gov/groups/STM/cavp/documents/rng/RNGVS.pdf

Successfully tested against both the cryptodev-2.6 tree and a Red
Hat Enterprise Linux 5.4 kernel, via 'modprobe tcrypt mode=150'.

The selection of 150 was semi-arbitrary, didn't seem like it should
go any place in particular, so I started a new range for rng tests.
