[PATCH 1/2] rootfs: clean rootfs dir before unpack from sstate

[Aliaksei Karpovich <akarpovich@ilbers.de>]

In case when rootfs is restored (unpacked) from sstate, we have to clean
rootfs dir because it can contain files from previous build which should
not be included in current rootfs and will not be deleted during unpack.
