[PATCH] classes/rootfs: remove content of /dev in postprocessing

[Quirin Gylstorff <Quirin.Gylstorff@siemens.com>]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

`/dev` is populated by the kernel/initrd during boot up and non
reproducable.

Use a seperate function as /dev must not be mount before the content
is removed.
