ui/dbus: on win32, allow ANONYMOUS with p2p

Browse source 
GLib doesn't implement EXTERNAL on win32 at the moment, and disables
ANONYMOUS by default. zbus dropped support for COOKIE_SHA1 in 5.0,
making it no longer possible to connect to qemu -display dbus.

Since p2p connections are gated by existing QMP (or a D-Bus connection),
qemu -display dbus p2p can accept authentication with ANONYMOUS.
