Wrong feature name in aai-service features.xml

Wrong feature name in aai-service features.xml

Even though this is part of CCSDK, the feature names used for CCSDK
in karaf are still following the convention of sdnc-, except for
aai-service.  This causes a problem since the install script expects
the feature names to start with sdnc-.  So, while it might arguably
be best to change all package names from sdnc-* to ccsdk-* and
update the installer, it is a smaller fix to just change aai-service
to use the sdnc- convention.
