entry-form.xsl: Correctly generate HTML for params with imported types

This is a nearly-10-year-old bug that was introduced when the Summary Page
was modified to use the then-new symbol table.  The compiler previously
concatenated all packages into a single XML tree and processed that, so no
package resolution was necessary here before.
