1. reflect GPLv3's presence in INCOMPATIBLE_LICENSE value in the UI
The hob UI currently only supports GPLv3 as a value for
INCOMPATIBLE_LICENSE but doesn't properly reflect whether the value is
already set. This patch rectifies this.
2. don't stomp over other INCOMPATIBLE_LICENSE values when disabling GPLv3
In case the user has other values set for INCOMPATIBLE_LICENSE we don't
want to overwrite the value, we want to modify it.
