pgsql: Back-patch 7.4-era fix for memory leak with SSL connections due

Log Message:
-----------
Back-patch 7.4-era fix for memory leak with SSL connections due to
missing X509_free() calls.  Per a request from a Red Hat customer;
seems silly for Red Hat to be shipping a patch that's not in upstream.
