tmux, vimrc: yanks also go to the local terminal clipboard via OSC 52

tmux: set-clipboard on, so OSC 52 written by vim inside a pane is forwarded
to the client terminal (external dropped it). vimrc: TextYankPost writes @"
as OSC 52 next to the existing ssh push; base64 via the base64 command since
base64_encode()/str2blob() are newer than vim 9.1.83.
