Update default contents of interwiki table

This list has obviously not been properly updated for many years. There
are many long-dead sites that are removed in this patch.

Removals will not affect existing wikis, only new wikis.

Also removing local designation for WMF wikis since this list is
intended for 3rd party users (WMF wikis have their own interwiki list).

Notes in square brackets should be checked again in the future.
