Pin bnd to 7.1.0 to work around Import-Service truncation in bnd 7.2+

maven-bundle-plugin 6.1.0 ships bnd 7.3.0. bnd >= 7.2.0 truncates
Import-Service filter attribute values at the first '=', which corrupts
the blueprint NamespaceHandler service filter and makes the generated
manifest unparseable at resolution time (IllegalArgumentException:
Unknown operator), failing ConfigExampleTest.testBlueprint.

Override the plugin's bndlib dependency back to 7.1.0 (last good release)
so the 6.1.0 bump can land until the regression is fixed upstream.
