Brad Fitzpatrick 2d2b62c400 wgengine/router: probe generally-unused "ip" command style lazily
This busybox fwmaskWorks check was added before we moved away from
using the "ip" command to using netlink directly.

So it's now just wasted work (and log spam on Gokrazy) to check the
"ip" command capabilities if we're never going to use it.

Do it lazily instead.
