Added password arg to set_shared_user_password.sh
BUG=none
TEST=Ran script, from within chroot, with no args(prompts for password),
one password arg, and multiple args(prints usage and exits), and each time
echo'd the password before it is encrypted. Each time it is correct. From
outside chroot, it only prints an error and exits.
