dropbear: drop support for DSA host keys in dropbear init script
Bring the dropbear init script into sync with the systemd service file (dropbearkey.service supports RSA host keys only) and with recent versions of openssh which deprecate DSA host keys. https://www.gentoo.org/support/news-items/2015-08-13-openssh-weak-keys.html Signed-off-by: Andre McCurdy <armccurdy@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
