Ticket #1732: add Docbook XSL and XML to check_alfs_tools

This is an oversight of when we moved to profiling and when we
removed the docbook xsl stylesheets from the LFS directory.
Docbook XML DTD and XSL stylesheets are needed, so test them
at start. This has the effect of removing the need for check_blfs_tools.
