Advance PG_CONTROL_VERSION.

Enterprise / PostgreSQL - Tom Lane [sss.pgh.pa.us] - 16 July 2016 11:49 UTC

This should have been done in commit 73c986adde5d73a5 which added several new fields to pg_control, and again in commit 5028f22f6eb05798 which changed the CRC algorithm, but it wasn't. It's far too late to fix it in the 9.5 branch, but let's do so in 9.6, so that if a 9.6 postmaster is started against a 9.4-era pg_control it will complain about a versioning problem rather than a CRC failure. We already forced initdb/pg_upgrade for beta3, so there's no downside to doing this now.
