Make pgstatindex respond to cancel interrupts.

Browse Source 
A similar problem for pgstattuple() was fixed in April of 2010 by commit
33065ef8bc52253ae855bc959576e52d8a28ba06, but pgstatindex() seems to have
been overlooked.

Back-patch all the way, as with that commit, though not to 7.4 through
8.1, since those are now EOL.
