netdb:fixed addrtype and length in gethostbyname

Browse Source 
Fix for the h_length field of struct hostent returned by gethostbyname() functions was returning 24 bytes instead of 4 and h_addrtype was returning AF_INET even for IPv6 address.

Closes https://github.com/espressif/esp-lwip/issues/50
