Enable request links for SSRC Velma Denning Room

[jkeck]

We coded this up, but commented out the location specific link work

https://github.com/sul-dlss/SearchWorks/blob/fb60d8add729d4fbbe6e43e670bc274acb644f51/app/models/request_link_factory.rb#L17

We haven't heard back from the SSRC folks, but once we do we need to:

• Uncomment the line above
• Ensure that request links are showing up on the correct location
• Validate that our config settings are correct

And this should be ready to go.

Still waiting on SSRC; they have their own form they're using.
