netdev-linux: Get carrier from ioctl instead of sysfs.

When a netdev Linux device is created or its netlink cache is
invalidate, it needs an alternative method to update the its
carrier status.  Previous patches retrieved this information from a
sysfs file.  This patch switches to ioctl which is significantly
simpler, and likely quite a bit faster as well.
