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.
