Add a "core/yocto/monitor-disk-space" fragment to enable the
functionality previously provided by the default definition of
BB_DISKMON_DIRS in local.conf.sample. As the definition might not be
obvious to set, having a simple way of enabling the feature through a
fragment makes it more approachable.
