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.
