Allow cache cleaning to process all cache directories 

Previously we only looked at the first cache directory returned by the
library. This allows us to look at all cache directories for cleaning.

In addition, change the way we do a full (-Scc) cache cleaning operation.
Instead of removing the parent directory, remove each package one-by-one as
in the -Sc case. This would be ideal for someone mounting a cache directory
over NFS, as it ensures we don't wipe out the mountpoint from underneath the
directory.
