Thread: pgsql: Add a couple of missed .gitignore entries.

Add a couple of missed .gitignore entries.

Any subdirectory that's ignoring /output_iso/ should also
ignore /tmp_check_iso/, which could be left behind by a
failed pg_isolation_regress_check run.

I think these have been wrong for awhile, but it doesn't
seem important to fix in back branches.
