proxy_gethostbyname(): fix failure to omit DNS lookup for ipv4 addrs 

gethostbyname() is specified to transform simple numeric ipv4 addresses
into their binary form. since proxy_gethostbyname() was used as a
backend for all resolver functions, somehow we assumed the check for
an ipv4 was done from another site, however this didn't hold true when
the caller used gethostbyname() directly.

fixes #347
