updates-proxy: disable filtering at all

Since this proxy is used only when explicitly configured in application
(package manager), there is no point in worrying about user
_erroneously_ using web browser through this proxy. If the user really
want to access the network from some other application he/she can always
alter firewall rules for that.

Fixes QubesOS/qubes-issues#1188
