[Peter Korsgaard]

Busybox 1.26.0 gained separate config options for swapon / swapoff:

commit f417ffd88f194bbfd18605882ee242190c1bab34

    Make swapon and swapoff individually selectable.

    For example, without swapoff, code shrinks by 277 bytes.

So adjust busybox.config and the logic to disable these applets for nommu
builds for the new names.
