lib/oe/sdk.py: Add SDKIMAGE_INSTALL_COMPLEMENTARY capabilities to DpkgSdk
Creating an SDK by means of do_populate_sdk, complementary packages
(SDKIMAGE_FEATURES = "dev-pkgs dbg-pkgs") are not installed when using
the deb packaging system.
The reason is that the call to install the complementary packages is missing
from the deb backend. This patch fixes that.
