This fixes an issue where the cache directory cannot be removed if it's a mountpoint. This commit tries removing the cache directory but doesn't fail if unsuccessful. Instead it tries removing the content of the cache directory. Should this fail as well, distrobuilder will issue a warning. The user is then responsible for cleaning up the cache directory. Fixes lxc#716 Signed-off-by: Thomas Hipp <thomas.hipp@canonical.com>
