osl.NewSandbox() always returns a nil interface on Windows (and other non-Linux
platforms). This means that any code that these fields are always nil, and
any code using these fields must be considered Linux-only;
- libnetwork/Controller.defOsSbox
- libnetwork/Sandbox.osSbox
Ideally, these fields would live in Linux-only files, but they're referenced
in various platform-neutral parts of the code, so let's start with moving
the initialization code to Linux-only files.

These functions were mostly identical, except for iptables being enabled
by default (unless explicitly disabled by config).
Rewrite the function to a enabledIptablesVersions, which returns the list
of iptables-versions that are enabled for the controller. This prevents
having to acquire a lock twice, and simplifies arrangeUserFilterRule, which
can now just iterate over the enabled versions.
Also moving this function to a linux-only file, as other platforms don't have
the iptables types defined.
