schema/ListedLicense: Punt license text into <text>

As it stands, there's not an easy way to extract the license text from
the XML format without removing crossRefs, notes,
standardLicenseHeader, and other siblings.  With this change (which,
if accepted, I still have to propagate into src/) we collect it in
<text>, just like we already collect the header text in
<standardLicenseHeader>.
