[Rpm-maint] [PATCH] Avoid warning about mbAppendStr if lui support isn't enabled.

[Mark Wielaard]

Guard the whole mbAppendStr function with ifdef WITH_LUA to avoid a
warning when lua support isn't enabled because it is only used inside
the doLua function (which is empty unles WITH_LUA is defined).
