Add a new "location" column to the pg_available_extensions and
pg_available_extension_versions views, exposing the directory where
the extension is located.
The default system location is shown as '$system', the same value
that can be used to configure the extension_control_path GUC.
User-defined locations are only visible for super users, otherwise
'<insufficient privilege>' is returned as a column value, the same
behaviour that we already use in pg_stat_activity.
I failed to resist the temptation to do a little extra editorializing of
the TAP test script.
Catalog version bumped.
