platform: Pass device fd into platform constructor.
We were previously openining the platform device (i.e. /dev/kvm) inside the
platfrom constructor (i.e. kvm.New). This requires that we have RW access to
the platform device when constructing the platform.
However, now that the runsc sandbox process runs as user "nobody", it is not
able to open the platform device.
This CL changes the kvm constructor to take the platform device FD, rather than
opening the device file itself. The device file is opened outside of the
sandbox and passed to the sandbox process.
