Stefan Fiedler:
	fix pkginstalled() for stage 0; the flist files are stored in
	a different location in this stage. 
	Hardly any package will need this, still it's good to always
	return correct results. 
	Note that since stage 0 uses a different root directory than
	all other stages, packages installed in stage 0 are not seen
	by pkginstalled() in later stages (unless installed again).
	AFAIK this is correct behaviour.
