Steam started taking advantage of newer fcntl commands, in particular `F_CREATED_QUERY`. This was causing our fcntl handler for 32-bit processes to assert out. Fixes the handler so it passes all other fcntl commands forward, just like the Linux kernel does. Splits the 32-bit handler to explicitly ignore a handful of commands just like the Linux kernel. Fixes an assert that Steam was hitting.
