Report invalid keysyms only when DEBUG_GENERATOR is defined.
It is not unusal that Qt applications are used on old linux
distributions where Compose files might be far behind the current
development, therefore we should be less verbose when encountering
invalid keysyms. On Red Hat 5 compose key plugin reports ~3200 lines of
warning messages:
"Qt Warning - invalid keysym: U1001D1BC"
"Qt Warning - invalid keysym: U1001D16F"
"Qt Warning - invalid keysym: U1001D1BA"
"Qt Warning - invalid keysym: U1001D165"
"Qt Warning - invalid keysym: U1001D16F"
