VNC clipboard sharing seems to be working fine on the krdc side here, at least with tightvnc/realvnc servers.
I have no idea if macOS's screensharing has any peculiar way to implement clipboard sharing, but googling for "macos screen sharing clipboard" brings up a lot of people claiming problems with it and possible solutions.

Can you please try to:
 * connect to any other vnc server, just to test if krdc clipboard sharing is actually working there;
 * check if any other vnc client has working clipboard sharing with your mac.

I just tried to VNC on Ubuntu Unity with KRDC, and it does work (though I discovered a problem with its graphics I'll open another report on)
