update-alternatives.bbclass: Add missing runtime dependency

When using update-alternatives, there should be a runtime dependency on
${VIRTUAL-RUNTIME_update-alternatives}.  Without this, it's possible to
get into a situation where the package is not installable.

(If VIRTUAL-RUNTIME_update-alternatives is not defined, no requirement
is added.)
