services: openssh: Replace 'without-password' by 'prohibit-password'.

For some time, OpenSSH's option 'PermitRootLogin' has deprecated the
ambiguous argument 'without-password' with 'prohibit-password'.

* doc/guix.texi (Network Services): Replace 'without-password by
'prohibit-password.
* gnu/machine/digital-ocean.scm (guix-infect): Change system
configuration to use 'prohibit-password.
* gnu/services/ssh.scm (openssh-configuration): Change comment to use
'prohibit-password.
(openssh-config-file): Add support for 'prohibit-password to
'permit-root-login'.  Warn about deprecated 'without-password usage.
* gnu/tests/ganeti.scm (%ganeti-os): Replace 'without-password by
'prohibit-password.
