[PATCH] html: add missing enumitem package

["Michael S. Tsirkin" <mst@redhat.com>]

makediffhtml.sh currently fails with:

! Missing number, treated as zero.
<to be read again>
                   \c@*
l.25850 \begin{enumerate}[label=\alph*
                                      .]
?
! Emergency stop.
<to be read again>
                   \c@*
l.25850 \begin{enumerate}[label=\alph*
                                      .]

Some web searches turned up suggestions to use enumitem and in fact,
virtio.tex already does this - but virtio-html.tex doesn't.

Adding \usepackage{enumitem} in virtio-html.tex too fixes the issue.
