Fix captive portal detection on IPv6 networks.

Currently the captive portal check URL is generated by
concatenating scheme, "://", IP address, and port. This breaks
for IPv6 because IPv6 addresses in URLs must be enclosed in
square brackets (e.g., http://2001:db8::1/generate_204 is
invalid; should he http://[2001:db8::1]/generate_204 instead).
The resulting MalformedURLException causes isMobileOk to report
that there is no captive portal, even if there is one.

Fortunately the three-arg URL constructor already knows how to
construct URLs with IPv6 addresses. Use that instead of
generating the URL ourselves.
