xapp-status-icon.c: Keep an account of button presses so an orphan

release doesn't activate or pop up a menu.

This happens in a situation where activating one icon (button press)
causes the icon to be removed, causing the subsequent button release
to be received by the adjacent icon, potentially activating its menu.
