Makefile.Watcom:

* The 'NTDDI_VERSION' needs to be raised to 0x05010000
    in order for SOCKADDR_STORAGE etc. to be typedefed.
  * Replaced '-dUSE_WATT32' with '-dWATT32'.
  * Added $(DEMOS) to the 'all' target and removed the 'demos'
    target to be consistent with e.g. Makefile.msvc etc.
  * 'ENABLE_IPV6' is no longer used. Hence removed the '%use_ipv6' construct.
  * object-file order seems to be important (Watcom v.19). Hence
    'ares_getopt.obj' must be put after the .obj that references getopt().
