command: add hmac sum supportfor md5, sha1, sha224, sha256, sha384, sha512
pass the key via -h param
barebox@barebox sandbox:/ sha256sum -h test /dev/fd0
c297473e9bb221c5dc51d47ad75c76095f1bdc4ca9dff1d5931c2e22bf11a0de /dev/fd0 0x00000000 ... 0xffffffffffffffff
use the same idea as openssl command
$ openssl dgst -sha256 -hmac "test" TODO
HMAC-SHA256(TODO)= c297473e9bb221c5dc51d47ad75c76095f1bdc4ca9dff1d5931c2e22bf11a0de
