Arch Linux

Description:
Conky now supports wayland ouput, it just needs "-D BUILD_WAYLAND=ON" cmake flag during its build to be enabled.
As more and more desktop environments are using wayland, I think it would be beneficial to enable its support.

This is a patch that seems to be working for me:

Additional info:
* package version(s)
conky == 1.18.1-1

* config and/or log files etc.
Example conky config to try drawing on wayland's background:

$ cat conky.conf
conky.config = {
out_to_wayland = true,
alignment = 'middle_middle',
own_window_argb_value = 0,
own_window_type = 'desktop',
default_shade_color = 'grey',
draw_shades = true,
font = 'Arial:size=13',
use_xft = true,
update_interval = 5,
}

conky.text = [[
${alignc}${font Arial:size=50:style=Bold}${exec date +"%H"}${font Arial:size=50}:${exec date +"%M"}${font}

${font Arial:size=20}${exec date +"%a %d %b %Y"}${font}
]]

* link to upstream bug report, if any

Steps to reproduce:
conky --config conky.conf
