Subject: passmenu: add support for wayland

Use a similar detection mechanism to pass itself.

On wayland use:

* dmenu-wl instead of dmenu, an (almost) drop-in replacement
* ydotool instead of xdotool, a uinput-based replacement for
  xdotool. It is not as feature-complete, but probably the
  simplest (or only?) way to add the --type functionality to
  passmenu on wayland.

+On wayland [dmenu-wl][] is used to replace dmenu and [ydotool][] to replace xdotool.
+Note that the latter requires access to the [uinput][] device, so you'll probably
+need to add an extra udev rule or similar to give certain non-root users permission.
