test/crypto: fix SNOW3G vector IV format

test/crypto: fix SNOW3G vector IV format

Some of the cipher and authentication IVs did not follow the spec for
SNOW3G algorithm [1].

Cipher IVs must have the last 3 bytes of each 8 byte block as 0x0.
IV[4] and IV[12] must have the last 2 bits set to 0.
Each 8 byte block is repeated.

Auth IVs must also have a repeated 8 byte block.
IV[8] and IV[14] may have a flipped bit based on direction.
