"git send-pack --stateless-rpc" puts each request in a sequence of pkt-lines
followed by a flush-pkt. The push option code forgot about this and sends push
options and their terminating delimiter as ordinary pkt-lines that get their
length header stripped off by remote-curl before being sent to the server.

The result is multiple malformed requests, which the server rejects.

Fortunately send-pack --stateless-rpc already is aware of this "pkt-line within
pkt-line" framing for the update commands that precede push options. Handle
push options the same way.
