Title: Mock: Don't store cache and chroot in workspace

This was originally done to make it possible to run builds from
different workspaces simultaneously on the same build machine.
However storing the chroot in the workspace has its own problems
(several hundred megabytes of root-owned files in the workspace).
Container techniques such as Docker or Vagrant are better solutions
to this problem.
