Bug 37368: Add 'library' to patron search embed

This patch adds the missing library embed from the patron search forms.
This embed is required for the case where a patron is missing both first
and last name or is from a different library group and thus falls into
the 'Patron from library X' block.

I also update the 'Patron from library X' to 'Patron from X' as I feel
it reads more clearly.

Finally, we need to sync the available embeds to ensure 'library' is
embeddable from the different endpoints this search can be triggered on.
