JVMCBC-1547 (followup) Exclude META-INF/services from repackaged dnsjava

Motivation
----------
Avoid dnsjava/dnsjava#329

We're not interested in overriding the JVM's default
DNS lookup mechanisms. All we care about is our own
explicit DNS SRV lookups.

Modifications
-------------
Don't include the `dnsjava` library's `META-INF/services`
directory in `core-io-deps`.
