condition: fix device-tree firmware path

Browse Source 
The path /sys/firmware/device-tree doesn't exist. This should be either
/proc/device-tree or /sys/firmware/devicetree.

The first path is only a link. So lets use the second path.

See https://github.com/torvalds/linux/blob/v4.14/drivers/of/base.c#L218.
