manifest: apply checkambig=True only for root 00manifest.i

This is a fix for my 14ad8e2a4abe, which used 'bool(dir)' as
checkambig value for revlog.__init__().

I can't remember why I did so in 14ad8e2a4abe, but this is obviously
wrong, because only root indexfile is cached via filecache-ed property
of localrepository.
