FFI: Make FFI call return nil when C function returns NULL
Before when a C function returned NULL pointer, an ExternalAddress with
address 0 wes returned which required an extra check in a caller to
convert it to nil, which would be the customary. This commit automatically
converts NULL pointers to Smalltalk `nil` as a courtesy to a Smalltalker.
