dropbear: disable MD5 HMAC and switch to sha1 fingerprints
As MD5 is known weak for many years and more and more penetration test tools complain about enabled MD5 HMAC I think it's time to drop it. By disabling the MD5 HMAC support dropbear will also automatically use SHA1 for fingerprints. This shouldn't be a problem too. Signed-off-by: Martin Schiller <ms@dev.tdt.de>
