Fix eplite node.js install problems.

Two problems installing node.js for etherpad lite on a new host:
1. Install may be attempted before repository is properly cloned.
2. Installing node from source may take longer than the default exec
timeout.

Fix this by adding more order requirements and increase the exec timeout
when running make on node.js.
