Fix integration test credential resource path handling (#11487)

This PR fixes an issue with the integration test copy_resources.sh script.

The "install druid jars" portion was removing the $SHARED_DIR/docker directory, which wipes out the $SHARED_DIR/docker/extensions and $SHARED_DIR/docker/credentials directories created just before, which leads to issues later in the script when copying resources to the $SHARED_DIR/docker/credentials/ dir.
