netwm: Do not use _NET_WM_PING in multi-screen
GDK dropped support for multi-screen several years ago.
Unfortunately, the code in GDK's _gdk_wm_protocols_filter() checks for
the default root window when dealing with _NET_WM_PING messages, and
that will cause an event loop when trying to use it on a multi-screen
setup.
Avoid the issue by not using _NET_WM_PING on multi-screen setups.
