Introduce a new "cache" subdirectory in the pmbootstrap workdir, all the cache and config bits go in here, anything that needs to be accessible from inside a chroot. The whole dir is then bind-mounted into the chroot as /cache with appropriate symlinks. This dir is in the config as config.cache. In addition, all the cache_* and other config dirs are renamed to be closer to the names of the equivalent dirs in the chroot (e.g. abuild-config) and to avoid redundant naming since they are now under a "cache" dir.
