Recent MinGW provides inet_pton(). There is our inet_pton()
implementation in src/inet.c. Our inet_pton() is declared in
src/inet.h but the declaration causes the following build error:

We already know that we don't need our inet_pton() for recent MinGW.
78a1657c7d (#300) removed
-DLUASOCKET_INET_PTON but LUASOCKET_INET_PTON in *.rockspec wasn't
removed.
It causes "luarocks install luasocket" for MinGW causes the above
build error.
