pgsql: Force archive_status of .done for xlogs created by dearchival/re

Force archive_status of .done for xlogs created by dearchival/replication.

This is a forward-patch of commit 6f4b8a4f4f7a2d683ff79ab59d3693714b965e3d,
applied to 9.2 back in August. The plan was to do something else in master,
but it looks like it's not going to happen, so let's just apply the 9.2
solution to master as well.
