[PULL 19/25] build: move vhost-vsock configuration to Kconfig

[Paolo Bonzini <pbonzini@redhat.com>]

vhost-vsock and vhost-user-vsock are two devices of their own; it should
be possible to enable/disable them with --without-default-devices, not
--without-default-features.  Compute their default value in Kconfig to
obtain the more intuitive behavior.
