recipetool: create: reimplement fetching with normal fetch/unpack tasks
Now that we have the ability to run the tasks in a more standard context through tinfoil, change recipetool's fetching code to use that to fetch files using it. This has the major advantage that any dependencies of do_fetch and do_unpack (e.g. for subversion or npm) will be handled automatically. This also has the beneficial side-effect of fixing a recent regression that prevented this fetch operation from working with memory resident bitbake. Also fix devtool's usage of fetch_uri() at the same time so that we can completely replace it. Fixes [YOCTO #11710].
