Suppress lintian warning about lsb-base dependency

This warning is erroneous since we do depend on lsb-base, we just also
depend on systemd-sysv as an alternative, since if that is installed,
the /etc/init.d/mandos script (which is the thing which actually
requires lsb-base) is never run anyway.  Suppress this warning.

* debian/mandos.lintian-overrides (mandos): Add new line
  "init.d-script-needs-depends-on-lsb-base etc/init.d/mandos (line
  49)"
