You can use 'gpart resize' and growfs. 

But why do you want to do this with the memstick image? It's for
installing FreeBSD, no?

# mdconfig -t vnode -a -f FreeBSD-11.0-CURRENT-amd64-20150618-r284544-memstick.img
md0
# gpart show md0
=>      3  1470064  md0  GPT  (718M)
        3     1600    1  efi  (800K)
     1603       32    2  freebsd-boot  (16K)
     1635  1466384    3  freebsd-ufs  (716M)
  1468019     2048    4  freebsd-swap  (1.0M)

In this case you first have to remove the swap at the end.
