[Buildroot] [PATCH] libglib2: Fix midori save file dialog not being rendered

[Valentine Barshak <gvaxon@gmail.com>]

This fixes the following issue, when midori
save file dialog is not rendered:
Neither the dialog nor the main window is redrawn
unless the save file dialog is closed.
The buttons can be blindly clicked though.

This is a known issue, which has been fixed in glib 2.32.2.

  gmain: block child sources when blocking the parent

  When blocking a source that has child sources, we need to consider the
  children blocked as well. Otherwise they will still trigger repeatedly
  in an inner loop started from the parent source's callback.
