BUG/MEDIUM: mux-h2: Handle EOM flag when sending a DATA frame with zero-copy

When a DATA frame is sent, we must take care to properly detect the EOM flag
on the HTX message to set ES flag on the frame when necessary, to finish the
stream. But it is only done when data are copied from the HTX message to the
mux buffer and not when the frame are sent via a zero-copy. This patch fixes
this bug.

It is a 2.4-specific bug. No backport is needed.
