qemu: domain: Modify <migrationSource> to look like <disk>

Browse Source 
When adding <migrationSource> I've used a slightly unusual approach. To
allow using the disk source XML parser and formatter convert
<migrationSource> to look like <disk>. This means that <source> will be
added as a subelement of <migrationSource> rather than being formatted
inline.

Conversion from the old format in the parser is very simple as it
involves only moving the XPath context current node slightly if the new
format is found.

The status XML to XML test shows that the upgrade is done correctly.
