add new extrausers command passwd-expire
This enhances extrausers with a new passwd-expire command that causes a local user's password to be expired as if the `passwd --expire` command was run, so the password needs to be changed on initial login. Example: EXTRA_USERS_PARAMS += " useradd ... USER; passwd-expire USER;" Tested: on useradd accounts When configured with Linux-PAM, console login prompts for and can successfully change the password. OpenSSH server works. Dropbear SSH server notes the password must be changed but does not offer a password change dialog and rejects the login request.
