dropbear: set DISTRO_TYPE to debug

* webos distro does not set any password and dropbear by default does
  not allow empty password and it cannot be changed in runtime config
  like in openssh.

* force DISTRO_TYPE to debug in this recipe, because
  DISTRO_TYPE ?= "${@base_contains("IMAGE_FEATURES",
  "debug-tweaks",
  "debug", "",d)}"
  does not work correctly when debug-tweaks is added to IMAGE_FEATURES
  in image recipe. It would work if you add debug-tweaks in
  EXTRA_IMAGE_FEATURES, because that's global.
