services: openssh: Fix 'PrintLastLog' default behaviour.
* gnu/services/ssh.scm (openssh-config-file): Add 'print-last-log?' option. (<openssh-configuration>)[print-last-log?]: Add it. (openssh-activation): Touch /var/log/lastlog. * doc/guix.texi (Networking Services): Document 'print-last-log?'. Before that, the service did not work as expected because /var/log/lastlog did not exist. Signed-off-by: Danny Milosavljevic <dannym@scratchpost.org>
