wutsocket: Revise automatic initialization, see details:

- socket_lib_init/exit wrappers are no longer stubs; they now perform
  refcounting & automatically register/deregister the socket devoptab
- Similarly, WHBInitialize/DeinitializeSocketLibrary are now aliased
  to socket_lib_init/exit
- WHBLogUdp now references socket_lib_init/finish again
- __init/fini_wut_socket have been simplified and are now weak,
  this is intended to allow users to customize their behaviour
