mod probe errors

Running ipkungfu v0.6.1 on 14.04 generates mod probe errors because the mod probe command in the script tries to use the -l options for mod probe which doesn't exist.
Replace the for loop which tries to load the default modules with a single line that just runs
                mod probe -a ${DEFAULT_MODULES_LIST} 2>&1 | logError
since our mod probe -a will load modules if necessary, and not complain if they are already loaded.
