Subject: [PATCH] [socketapi] Replace QClipboard with KSystemClipboard when
 available

This is necessary in Wayland sessions for the clipboard related actions
of the socketapi to work. Indeed, QClipboard does its job only if we got
a window with the focus in such session.

In the case of the socketapi, it is generally the file manager asking
the desktop client to put something in the clipboard. At this point in
time no window of the client have the focus, so nothing gets added to
the clipboard.

KSystemClipboard on the other hand, uses the wlr data control protocol
under wayland sessions ensuring something ends up in the clipboard as
expected. When not in a wayland session it falls back to QClipboard so
no behavior is lost.
