allow colorizing only directories but it is more portable.
NOTE: `helm-list-dir-external' needs ls and awk as dependencies.
Also the ls version installed on the remote side should support
the same arguments as the GNU/ls version, which are -A -1 -F -b

want to connect e.g. on a Freebsd server, you may have failures
