Patch up the includes for the KDE3 network compatibility classes as best as I can without reworking any code, and tell krazy to ignore the fact the files don't include their own headers first.

I don't think it's worth fixing these properly, especially given that netsupp.h isn't installed, k3socks.h isn't a public interface (you even have to define I_KNOW_KSOCKS_ISNT_PUBLIC to use it), and the syssocket.h thing is a peculiar work around for some stupid preprocessors and k3socketdevice.h doesn't need it to be used by users of the library (syssocket.h isn't installed).
