Hard code freeze break for gnome-panel

[Vincent Untz <vuntz gnome org>]

Hi,

While debugging some accessibility issue, I found out that if you press
alt+f1 to open the main menu (when you only have the main menu, not the
menu bar), it doesn't work. It turns out the logic for finding if a menu
button is a main menu was inverted.

It's really extremely simple :-)

The logic was inverted.
