qemuxmlconftest: Add testing of FDs with 'writable' flag in 'disk-source-fd'
Add few examples of fd groups with the 'writable' flag set, when passing a single FD. Notably as a top level image of a readonly disk (even when that doesn't make much sense) and also as a base image of a chain. Note that this documents a status quo of a bug fixed in upcoming patch.
