[gtkmm] RGBA: set_grey(), set_grey_u(): Correct the default alpha values.

[Murray Cumming <murrayc src gnome org>]

commit a1f0d0e0000f960d34ed602243cab252d5f82214
Author: Murray Cumming <murrayc murrayc com>

    RGBA: set_grey(), set_grey_u(): Correct the default alpha values.
    
    * gdk/src/rgba.hg: The default values for these two methods were
    swapped. This could cause some slight change of behaviour in
    existing applications, but the previously wrong values should
    have been obvious, and corrected, in applications already.
    Bug #671573 (Mark Vender)
