platform/tests: ignore ip-tunnel interfaces in nmtstp_assert_platform() 
Certain ip-tunnel modules automatically create network interfaces (for
example, "ip_gre" module creates "gre0" and others).

Btw, that's not the same as `modprobe bonding max_bonds=1`, where
loading the module merely automatically creates a "bond0" interface. In
case of ip tunnel modules, these generated interfaces seem essential to
how the tunnel works, for example they cannot be deleted. I don't
understand the purpose of those interfaces, but they seem not just
regular tunnel interfaces (unlike, "bond0" which is a regular bond
interface, albeit automatically created).

Btw, if at the time when loading the module, an interface with such name
already exists, it will bump the name (for example, adding a "gre1"
interfaces, and so on). That adds to the ugliness of the whole thing,
but for our unit tests, that is no problem. Our unit tests run in a
separate netns, and we don't create conflicting interfaces. That is, an
interface named "gre0" is always the special tunnel interface and we
can/do rely on that.

Note that when the kernel module gets loaded, it adds those interfaces
to all netns. Thus, even if "test-route-linux" does not do anything with
ip tunnels, such an interface can always appear in a netns, simply by
running "test-link-linux" (or any other tool that creates a tunnel) in
parallel or even in another container.

Theoretically, we could just ensure that we load all the conflicting
ip-tunnel modules (with nmtstp_ensure_module()). There there are two
problems. First, there might be other tunnel modules that interfere but
are not covered by nmtstp_ensure_module(). Second, when kernel creates
those interfaces, it does not send correct RTM_NEWLINK notifications (a
bug), so our platform cache will not be correct, and
nmtstp_assert_platform() will fail.

The only solution is to detect and ignore those interfaces.  Also,
ignore all interfaces of link-type "unknown". Those might be from other
modules that we don't know about and that exhibit the same problem.
