[libvirt] [PATCH 2/4] docs: Introduce $(devhelphtml_generated)

[Andrea Bolognani]

Our XSLT magic generates one Devhelp-compatible HTML file
per documentation module, but so far we have only shipped
and installed documentation for virterror.

Now that we have $(modules), however, we can generate the
list of files the same way we do for regular documentation
and make sure we always ship and install everything.
