[PATCH] Rebuild after cleaning does not work anymore, bugfix v2

[roberto.foglietta@gmail.com]

From: "Roberto A. Foglietta" <roberto.foglietta@gmail.com>

bugfix, image and rootfs classes, fails in rebuilding - rebuild after cleaning
does not work anymore but it is required to remove manually all the directories
and this would take longer to rebuild. This patch fixes this new wrong
behaviour which happens when the kernel is not compiled but installed.

Reproducibility: this sequence of commands does not work anymore

kcbuild
./kas-container --isar clean
     XOR/AND
sudo ./kas-container clean
kcbuild

It fails with error while the following still works

kcbuild
sudo rm -rf build/tmp build/sstate-cache
kcbuild

but it takes more time than the previous when it was working.
