Pepper: Remove url_info_map from trusted plugin.

This appears to be a vestigal part of some StreamAsFile() operation that no
longer exists. It's not necessary to cache this file info in the plugin, as we
only ever return it once.

I've split this off from a bigger StreamAsFile() refactoring to make the diff
smaller, to help debug Windows failures on that patch.
