Bug#1141420: openssh-client: /usr/share/doc/openssh-client is an absolute symlink after upgrade

Package: openssh-client
Version: 1:10.3p1-8

Upgrading from version 1:10.3p1-5 turns /usr/share/doc/openssh-client
into a symlink, but it is an absolute symlink rather than a relative one
as recommended by policy and shipped by the package:

I think in debian/*.maintscript a relative path for the symlink target
ought to be used, but I have not tested that.  Suggested patch:

sed -i 's#/usr/share/doc/openssh-common#openssh-common#' debian/*.maintscr=
