Tobias Urdin efffd27a41 Add old ruby support to inet6_prefix
When running an older version of Ruby that has
an old version of ipaddr this function fails with
a uninitialized constant IPAddr::AddressFamilyError
error.

This can happen if you are for example running this
code from inside a Puppetserver that runs under JRuby
that has an older version of ipaddr.

This adds a check if one of the classes that was introduced
to replace the ArgumentError exception is present and customizes
the exceptions we catch based on that.

# Add inet6 prefix if the argument is an IPv6 address.

# This is useful for services relying on python-memcached which require
# the inet6:[<ip_address]:<port> format.
#
# Returns the argument untouched otherwise.
