    postinst: refactor user creation
    The current user creation logic has a couple of drawbacks:
     - It uses a loose match against /etc/passwd. The grep call will match
       anything with the "mongodb" word in it, and it also assumes that
       /etc/passwd is the only NSS source on the system.
     - The mongodb user has nogroup as its primary group
     - The mongodb user has a valid shell
    Replace the user creation with a single, unconditional call to adduser
    which will succeed if the mongodb system user exists (even if previously
    created with `nogroup' as the primary group).
