esx: Allow connecting to IPv6 server

When connecting to a VMWare server, the hostname from URI is
resolved using esxUtil_ResolveHostname() which in turn calls
getaddrinfo(). But in the hints argument, we restrict the return
address to be IPv4 (AF_INET) which obviously fails if the address
to resolve is an IPv6 address. Set the hint to AF_UNSPEC which
allows both IPv4 and IPv6. While at it, also allow IPv4 addresses
mapped in IPv6 by setting AI_V4MAPPED flag.
