I'd suggest you don't remove it - from sshd(8):

     /var/empty
             chroot(2) directory used by sshd during privilege separation in
             the pre-authentication phase.  The directory should not contain
             any files and must be owned by root and not group or world-
             writable.


If you intend to run sshd in your jail, you'd be better off leaving it.
