[glibmm] MountOperation: Correct an ABI break.

[Murray Cumming <murrayc src gnome org>]

commit 3bdf0fe4b189655a0d3656a5e70b369ca379e7d4
Author: Murray Cumming <murrayc murrayc com>

    MountOperation: Correct an ABI break.
    
            * gio/src/mountoperation.hg: Use the no_default_handler option with
    the new _WRAP_SIGNAL() to avoid a new on_*() vfunc increasing the size
    of the class. This got into the 2.34.0 release at the last moment
    but it seems better to correct it before people use it than to leave it.
