Subject: [PATCH BlueZ 2/5] test-crypto: Add /crypto/sih test

From: Luiz Augusto von Dentz <[email protected]>

This adds test /crypto/sih which validas the implementation of
bt_crypto_sih using the sample data from CSIS[1] spec:

A.1. sih Resolvable Set Identifier hash function

> unit/test-crypto -s "/crypto/sih"
K:
cd cc 72 dd 86 8c cd ce 22 fd a1 21 09 7d 7d 45 ..r....."..!.}}E
R:
63 f5 69 c.i
Expected:
da 48 19 .H.
Result:
da 48 19 .H.
