[swaybar] fix non-dbus build

Swaybar's CMakeLists.txt uses the enable-tray option directly to decide whether to build the tray. This leads to a compilation error if dbus is not installed.
This patch uses the ENABLE_TRAY variable instead, which is only true if the user enabled the tray *and* dbus is available.
