tests: Add CAVP test vectors for byte-oriented SHA-1 and SHA-256

Browse source 
This allows the SHA-1 implementation to be validated against the
SHA1ShortMsg.rsp and SHA1LongMsg.rsp test vectors from
http://csrc.nist.gov/groups/STM/cavp/documents/shs/shabytetestvectors.zip.
Similarly, the SHA-256 can be validated against the SHA256ShortMsg.rsp
and SHA256LongMsg.rsp.
