Prefer using the character device over the proc file if the character
device exists.

So this was originally submitted with 9c89dc95201 and 7d418eab3b6 and
was rejected since the goal was to convert gdbsx to use libxc but that
hasn't happened. /dev/xen/privcmd should be preferred and this change
makes that happen. It would be nice if we landed this with the plan
to convert gdbsx happening when it happens.
