[bash] improve ls aliases

Browse source 
When the GNU version of `ls` is not installed (e.g. on a new Mac), the
previous alias causes problems because the --group-directories-first
option is not supported and makes `ls` fail. This commit fixes that by
checking which version is installed and creating the alias accordingly.
