Bump org.apache.aries.blueprint.core version

From 1.4.2 to latest 1.7.1, because in
org.opendaylight.controller:blueprint version 1.7.1 was already used
anyway, and indeed this appears to be the version used in our current
version of Karaf, and it seems wiser to declare this in only a single
place, to avoid possible version discrepancy problems re. this artifact
in the future.  So let's just bump this one, and drop the version in
controller:blueprint in a follow-up change.
