lukeg ba55706fb6 fix test/rubygems/test_gem_package_task.rb when in -j mode
This test skipped sometimes due to failure to load 'rake/packagetask'.
This is due to manipulation of $LOAD_PATH by other rubygems tests. If
rake is loaded before any rubygems tests run, then it works fine.

To reproduce the skipping behavior:
  $ make test-all TESTOPTS="-j6 --test-order=sorted test/rubygems/test_*.rb"
