cilium/cmd: remove unnecessary parseLabels func
cilium/cmd: remove unnecessary parseLabels func

The parseLabels func mereley checks for the slice passed to it not to be
empty. All call sites are already protected by "if len(slice) > 0", so
drop parseLabels entirely and directly append the checked slice to
srcSlices/dstSlices.
