Revert "libnma: drop use of GtkWidget.no-show-all property"

This breaks gnome-control-center and nm-connection-editor,
which call gtk_widget_show_all().

Two offending gtk_widget_show_all() calls by nm-connection-editor
were removed in response to this. Which fixes the main issue for
new nm-connection-editor. These two patches were were also reverted.

It's not acceptable to break existing users of libnma. Even if they
possibly should be fixed.

For the moment, just revert the patches.

This reverts commit 07d900c0.
