recovery: install packages in a known mount environment
When installing a package, we should have /tmp and /cache mounted and
nothing else. Ensure this is true by explicitly mounting them and
unmounting everything else as the first step of every install.
Also fix an error in the progress bar that crops up when you do
multiple package installs in one instance of recovery.
