[libvirt] [jenkins-ci PATCH 4/5] guests: Create ccache symlink farm

ccache can detect the name it's been called with and transparently invoke the compiler if it matches. The Fedora package uses this trick to enable ccache out of the box, but other operating systems and distributions leave the task up to the user. Replicate the setup in the user's ~/.ccache directory so that it works across all guests. With the linke farm in place, setting $CC in the user's shell profile is no longer necessary.
