rootfs.py: support BAD_RECOMMENDATIONS for ipk incremental image generation

Browse Source 
While incremental image generation enabled and the previous image is
existed, if BAD_RECOMMENDATIONS is changed, the operation on the
existing image is complicated, so remove the old image in this situation.

The same with PACKAGE_EXCLUDE and NO_RECOMMENDATIONS.
