[libvirt PATCH] news: Document that we build with musl

[Martin Kletzander]

A bit of effort by me and Michal helped make this the case, and it helped us
uncover some potential issues.  I am not documenting it as supported or adding
an Alpine container into the CI, but since there were some distribution bugs
mentioning libvirt issues I thing it would be nice of us to notify those
distribution maintainers that read our release news.
