Changes to mkurl to avoid "escaping" oils wrapper

Port changes to mkurl macro to avoid "escaping" the oils wrapper.

Observed symmptom was that we were no longer in "staff mode" in the

Skip Piwik tracking for staff

This change may be temporary. Since we do not currently have an
approach for incorporating Piwik tracking code in the catalog
interface within the staff client (within the oils:// protocol
wrapper), omit Piwik tracking code when is_staff is true.
