pg_dump: Don't leak memory in buildDefaultACLCommands()
buildDefaultACLCommands() didn't destroy the string buffer created in
certain cases, leading to a memory leak. Fix by destroying the buffer
before returning from the function.
Spotted by Coverity.
Author: Michael Paquier
Back-patch to 9.6 where buildDefaultACLCommands() was added.
