[sb2] Clean correctly without breaking builds and keeping the tree dirty

Previously config.status was also clean as part of the clean making
rebuilds impossible without calling configure again.
Clean isn't supposed to clean the generated build- or
distribution-system files.

Further somefiles that should be clean where not cleaned at all.
This change also aligns the name of the clean target which removes
the distribution to the one configure mentions when it fails.
