sysutils/plasma5-ksysguard: lighten dependencies

- kdelibs4support is unused

Bumping PORTREVISION here to force a rebuild; the idea is
that we want to reach a situation where kdelibs4support
can be removed by `pkg autoremove` as soon as it isn't
consumed by anyone (although this will require upstream work first).
