qtvcp -pushbutton: fix setting of group pin type

Enums are evil in Qt.
if the class enums variable use the same definition, it silently
breaks the setting of the pin type.
so PinType class can be:

    NONE = 0
    BIT = hal.Type.BOOL # Deprecated <<<<<
    S32 = hal.HAL_S32
    FLOAT = hal.Type.REAL # Deprecated <<<<
    BOOL = hal.Type.BOOL
    SINT = hal.Type.SINT
    REAL = hal.Type.REAL

but class variables must be:
    NONE = 0
    BIT = hal.HAL_BIT # Deprecated <<<<
    S32 = hal.HAL_S32
    FLOAT = hal.HAL_FLOAT # Deprecated <<<<<
    BOOL = hal.Type.BOOL
    SINT = hal.Type.SINT
    REAL = hal.Type.REAL

Don't know why.
