(SERVER-1630) Remove jruby exclusions from jruby-utils dep
(SERVER-1630) Remove jruby exclusions from jruby-utils dep

Previously, for the jruby-utils dependency, explicit exclusions were
included for various jruby-related dependencies - jruby-core,
jruby-stdlib, jffi, and jnr.  jruby-utils itself, though, no longer has
any explicit dependencies for any of these.  Instead, the jruby-deps
dependency controls which/whether any of the jruby-related dependencies
are pulled in.  This commit removes the exclusions for these
dependencies from the jruby-utils dependency since they are no longer
needed.
