docs: xsl: Don't format empty sections in API manual

Browse Source 
The LXC module has no exported 'Types' but the XSL template which
generates the 'libvirt-libvirt-lxc.html' page would try to format it
anyways. This would result in an empty non-pair version of the '<pre>'
tag to be used in the page, which didn't render well with modern
browsers for some reason. All following sections would become children
of the non-pair <pre>.

Fix the XSL template to not generate empty 'Types' or 'Functions'
sections similarly to how we do with 'Macros'.
