[gimp] libgimp: GValue of type GEnum not possible.

    libgimp: GValue of type GEnum not possible.
    
    This fixes such warning:
    > Warning: gvalue.c:188: cannot initialize GValue with type 'GEnum',
    > this type is abstract with regards to GValue use, use a more specific
    > (derived) type
    
    And obviously all subsequent errors because we failed to initialize and
    set enum values. Such as:
    
    > Warning: g_value_set_enum: assertion 'G_VALUE_HOLDS_ENUM (value)' failed
    
    I have only fixed this in gimp_image_pdb. If enum types are used in
    other places with GimpValueArray, we must fix them the same way.
