Fix downloads failing due to duplicate SSRF filters

ssrf_filter v1.0.8 patches `SSLSocket#hostname=` to protect against
server side request forgery (SSRF) attacks. We do the same thing in
`gems/gitlab-http/lib/hostname_override_patch.rb`, except ssrf_filter
lazily patches the request upon first use with CarrierWave. When both
patches are activated, the process fails to download the file and
reports `stack level too deep`.
