ccache: allow for BR2_CCACHE_DIR environment override
Allow the BR2_CCACHE_DIR .config option to be overriden by the
BR2_CCACHE_DIR env variable.
This is useful for big projects where in some cases the developers home
directory might be a NFS mount (slow) and real production builds aren't.
Update documentation accordingly as well.
