pg_upgrade: don't copy/link files for invalid indexes

Browse Source 
Now that pg_dump no longer dumps invalid indexes, per commit
683abc73df, have pg_upgrade also skip
them.  Previously pg_upgrade threw an error if invalid indexes existed.

Backpatch to 9.2, 9.1, and 9.0 (where pg_upgrade was added to git)
