Small fixes to feature files.

As it turns out... the default artifact type
for config files is jar from commons/opendaylight/pom.xml

This is not corrected there because jar *is* the thing that
is used by the legacy distributions...

But if we don't correct it here, if you try to test a feature
against an empty .m2... the test will fail.

(Yes, this is how I spend my evenings, emtpying out my .m2
directory :( )
