File bmalloc/Zone.cpp is required on Darwin irrespectively from what port is being built. Also I removed WEBKIT_INCLUDE_CONFIG_FILES_IF_EXISTS() because it's unlikely that bmalloc will ever need port-specific customizations (as opposed to OS-specific customizations which should be done in CMakeLists.txt).
