initscripts: check if swapon/swapoff exists before executing them
Not all built images contain swapon/swapoff, for instance, it is
configurable with or without them in busybox. So it'd better to check if
they exist or not before executing them.
Redirecting the potential errors to /dev/null is not good enough, which
might suppress the *real* errors.
