Consider ::ffff:127.0.0.1 as a loopback address

Browse Source 
cpp-httplib  sets IPV6_V6ONLY to false on it's sockets.
On FreeBSD, this makes all ipv4 addresses get get prefixed with ::ffff:
it makes them IPv6 addresses mapped to v4.

This is a partial fix for #2151. The cli will work again.
Something should probably also be adjusted with the httplib.

If you want to, for example, use the `allowManagementFrom` option in
local.conf
you will need to prefix it with "::ffff:", "::ffff:1.2.3.4"
which is a little surprising and inconsistent between BSD and other OSs.
