Bump minimum IO::Socket::IP version to 0.32

Fixes #49

The following error is fixed:

$ .../perl-5.20.2/bin/perl -Mblib t/url.t
url: http://[::1]:13381/
599 Internal Exception
Could not connect to '[::1]:13381': IO::Socket::INET: Bad hostname '[::1]'

As explained by @DrHyde: "IO::Socket::IP only went into core in 5.19.8,
and 0.32 was in 5.21.4, so aside from dev releases, only 5.20.x are
affected by this."
