vendorcode/eltan/security/lib: Implement SHA endian function
digest from vb2_digest_bufer() does not contains the correct endian.
Create cb_sha_endian() which can convert the calculated digest into big endian
or little endian when required.
BUG=N/A
TEST=Created binary and verify logging on Facebok FBG-1701
