libcamera: signal: Fix compilation on gcc

gcc complains that the recently template specialisation of the
SlotBase::match() method is invalid as it is in a non-namespace scope.
Luckily this can easily be fixed by removing the specialisation for the
fully specialised implementation. As an additional safety measure, using
std::enable_if<!std::is_same<Object, T>> on the template implementation
ensures that it will never be called for an Object instance.
