Bug 10379 - Followup: add koha-rebuild-zebra -q to the man page

The first patch on this bug forgot to add the new -q option to
koha-rebuild-zebra to the man page for that command. This patch
fixes it.

To test, run something like these commands:

$ xsltproc /usr/share/xml/docbook/stylesheet/docbook-xsl/manpages/docbook.xsl \
  debian/docs/koha-rebuild-zebra.xml
$ man -l koha-rebuild-zebra.8
This should display the man page. (Remember to remove koha-rebuild-zebra.8
when you are done :-)

$ prove xt/verify-debian-docbook.t
All tests should pass.
