dropbear: allow configuring blank password option at runtime
Instead of using IMAGE_FEATURES to control something within a recipe, allow this to be set at runtime, avoiding the need to rebuild dropbear when we want to change this option. First half of the fix for [YOCTO #2578]. Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Saul Wold <sgw@linux.intel.com>
