Add sql to create test-system-curator for auto workflow processing
When installing dryad test environment, use cp -L to deref symlinks

workflow.xml and workflow-actions.xml are symlinked in the source tree, but Linux and OS X have default behaviors for `cp -r` when finding symlinks. Linux copies the links, OS X dereferences them.

`cp -L -r ...` fixes this, and now the tests for automatic-release-blackout succeed.
