Bug 10622 - [SIGNED OFF] Followup: Add --sip, --nosip and --help to man page

The original patch for bug 10622 added the --sip, --nosip and
--help switches to the koha-list command, but did not update the
manpage for the command. This patch does.

To test:

Run these commands and look at the formatted man page:
$ xsltproc /usr/share/xml/docbook/stylesheet/docbook-xsl/manpages/docbook.xsl \
  debian/docs/koha-list.xml
$ man -l koha-list.8

Make sure this test passes:
$ prove -v xt/verify-debian-docbook.t
