Subject: [PATCH] wayland: check activation supported before activating

It's possible for token to be set when the compositor doesn't support
activation, and this caused a segfault.  For example, this can happen
when overriding WAYLAND_DISPLAY to point to a compositor that doesn't
support activation, in a terminal running under one that does, and so
has set XDG_ACTIVATION_TOKEN.
