Find docbook-xsl and dblatex templates on Red Hat/Fedora

Michal Nowak requested to merge mnowak/Red_Hat_find_docbook-xsl into master

Remove unused configure checks for dblatex.

Find docbook-xsl and dblatex templates on Red Hat/Fedora: /usr/share/sgml/docbook/xsl-stylesheets and /usr/share/dblatex are places where docbook-style-xsl and, respectively, dblatex packages on Red Hat systems put their XSL templates. Unless we hint this place it has to be added to ./configure manually (--with-docbook-xsl=...): https://src.fedoraproject.org/rpms/bind/blob/master/f/bind.spec#_691.

On Fedora 30:
