recipetool: create: eliminate second fetch for packages
When dealing with package files (.rpm, .ipk etc.) we need to unpack them
ourselves to get the metadata, which is thrown away when the fetcher
unpacks them. However, since we've already fetched the file once, I'm
not sure as to why I thought I needed to fetch it again - we can just
get the local path and then unpack it directly.
