Provide for contrib and pgxs modules to install include files.

Browse Source 
This allows out-of-tree PLs and similar code to get access to
definitions needed to work with extension data types.

The following existing modules now install headers: contrib/cube,
contrib/hstore, contrib/isn, contrib/ltree, contrib/seg.
