Documentation: move Documentation/virtual to Documentation/virt

2019-07-24T08:52:11Z

Renaming docs seems to be en vogue at the moment, so fix on of the grossly misnamed directories. We usually never use "virtual" as a shortcut for virtualization in the kernel, but always virt, as seen in the virt/ top-level directory. Fix up the documentation to match that.
