[libvirt] [PATCH] Replace <optional><oneOrMore> with <zeroOrMore>.

[Diego Elio 'Flameeyes' Pettenò]

The two syntax should be equivalent, but the former creates, with trang, an
invalid Relax-NG Compact form file, as the output will contain the sequence
"+?" which is not recognized by tools like rnv.
