I split the fetch phase into a separate command. This should make it
easier to see that the dependency failed because it was unable to fetch
the distfiles.

This will also no longer update the failcache, as fetching could be a
temporary problem.

This should also remedy the situation on legacy systems for now.
Installation as a dependency will be retried even if a previous run
failed due to fetching. By that time, the distfile was hopefully
uploaded to the mirror.

We should still investigate in adding a master_site_local, as this
involves more fetches from the internet than necessary at the moment.
