The virtiofs project started off using "virtio-fs" but later switched to
the "virtiofs" spelling because it matches the spelling of the mount -t
virtiofs command-line. Update the kbase article with the new spelling so
it matches the virtiofs website.

A number of legacy issues make the virtiofs kbase article hard to
understand. Most users don't need to configure NUMA or a memory backend
other than memfd. Move that information to the bottom of the article so
the recommended syntax is most prominent.

When adding support for externally launched virtiofsd,
I was too liberal and did not require a target.
But the target is required, because it's passed to the
QEMU device, not to virtiofsd.

Nowadays memfd is the most convenient memory backend for vhost-user
devices. Compared to file-backend memory and hugepages, there is no need
to worry about configuring the location of the shm directory or
allocating hugepages.

Using virtiofs without NUMA was implemented in v6.9.0-rc1~161 but
our kbase document only mentions QEMU version which may confuse
users.

Reflect in the virtiofs documentation that virtiofs can now be used
even without NUMA. While at it, be more precise where and why shared
memory is required.
