description:
improve the (#ifdef DEBUG_LINUX) socketcall argument dump code:
- print the socketcall type
- special case socket(2) call, it's also the only one with first argument
  not being a socket descriptor
- only dump the relevant part of linux_socketcall_dummy_args, instead
  of always the whole structure
