pgsql: Fix pg_upgrade to handle event triggers in extensionscorrectly.

Fix pg_upgrade to handle event triggers in extensions correctly.

pg_dump with --binary-upgrade must emit ALTER EXTENSION ADD commands
for all objects that are members of extensions.  It forgot to do so for
event triggers, as per bug #15310 from Nick Barnes.  Back-patch to 9.3
where event triggers were introduced.
