Subject: [PATCH] sysusers: use "!*" instead of "!!" as an invalid group
 password

This basically implements fc58c0c7bf7e4f525b916e3e5be0de2307fef04e for gshadow.
gpasswd may not have a lock/unlock that behaves the same as passwd, but
according to gshadow(5) the logic of the password field is the same.
